Description of the Invention (1) [Background of the Invention] 1. Field of the Invention The present invention relates to a step of plating a strip continuously moving on a plating line, and a method and device for controlling the weight of metal paint. 2. Conventional devices related to conventional technology used to control the weight of metal coatings, such as those disclosed in the "Steel Engineer" published in June 1994, are used to control some parameters, such as the pressure of the gas emitted from the nozzle and the height of the nozzle ; The distance (gap) from the nozzle to the strip is determined by the control model equation or the like after changing the coating weight specification, and the feedforward control is exercised according to some control parameters. After the specification change point is provided to a paint weight sensor, and the detection corresponding to the new specification has been obtained, the deviation between the detection corresponding to the new specification and the target paint reset is detected, and a Feedback control is performed to reduce deviation. However, this conventional technique has the following disadvantages.

I 首先，在前饑控制方面的問題爲，若是控制標的假設 値和計算控制參數時之眞正測量値有偏差時，此一偏差就 會使塗料重量不精確。 另一問題爲由於控制參數之計算係固定使用預先建立 之控制模型，使得控制標的狀態之材齡變異、控制環境等 等無法補償，而使得塗料重量不精確。 此外，無法保證預先建立之控制模型是已考慮所有精 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） 經濟部中央標準局員工消費合作社印装 418993 b7 五、發明説明（2 ) 確度改良之控制模型。有時控制模型因標的塗料重量而含 有很大誤差 同時，在回饋控制方面，無用時間之補償主要是因爲 從噴嘴位置到塗料重量感應器之附接位置未列入考盧。因 此，在更換參數之後（執行回饋控制一次），在條片更改 部分到達塗料重量感應器之後有必要再度執行回娥控制。 塗料重惫的精確度改良亦因此受限。 此外，若以塗料重量感應器來掃瞄條片寬度方向而產 生塗料重量平均値，由於得用好幾十秒來取得塗料重量平 均値，其偵測延遲時間很長。另一方面，若固定掃瞄條片 的代表性位置（例如中央），雖然偵測延遲很短，但有時 因條片外形會有很大的偵測誤差値。 〔發明槪述〕 因此，本發明目的之一在克服傳統技術缺點並提供控 制方法和裝置來使金屬塗料重量很精確和均一。 上述之問題係由下述本發明之構造來解決。 控制檫的假設値在計算控制參數時與眞正値不相等的 問題之解決方式是提供：觀察裝置用來在控制時間接收控 制標的之狀態變異，並估計該控制狀態下之金屬塗料重量 ;以及觀察控制裝置，用來修正一控制參數，該控制參數 爲依據覩察裝置之输出和標的塗料重量之間的偏差。 當參數係給定爲嘖嘴位置和實化標的塗覆重置之氣體 壓力的組合時，觀察控制裝置修正噴嘴位置和氣體壓力， 本紙浪尺度適用中國國家標準（CNS > A4規格（210X297公釐）-5 - (請先閱讀背面之注意事項再填寫本頁) l·裝· 訂 經濟部中央標準局貝工消費合作社印裝 418993五、發明説明（3 )以減少偏差。 此外亦.提供修正函數計算裝置，以計算用於塗料重量 之氣體壓力或噴嘴位置之預定關係値，亦即改變之程度， 而噴嘴位置和氣懺壓力參數之修正係使用一値，而該値係 將該預定關係値乘以偏差。 此外亦提供模型誤差收集裝置，用來貯存控制模型預 估塗料重量値和塗料重量感應器眞正量測値之間的差異。 固定使用控制模型之問題之解決係藉由使用該差異來修正 使用控制模型之控制參數計算裝置和觀察控制裝置二者的 計算結果。 控制模型有誤差之問題的解決係藉由：提供多個控制 模型，並侬據檫的塗料重量來選擇控制模型。 回餹控制的長無用時間問題之解決係藉由：以塗料重 童感應器輸出和觀察裝置無用時間前输出來補償_察裝置 之輸出。 因塗覆重量感應器操作模式導致偵測延遲時間增加或 不精確之問題的解決係藉由提供：一外形貯存裝置來貯存 塗料外形（依條片寬度方向）；以及塗料重量修正裝置， 其參考外形貯存裝置之內容來修正塗料重置感應器感應之 値0 以下介紹本發明上述結構之操作。 觀察裝置估計目前控制狀態使用之金羼塗料重量，其 估計所依靠者爲狀態變數，例如條片移動速度、噴嘴位置 、氣體壓力等由控制標的偵測所得者。觀察控制裝置以標 (#先閱讀背面之注$項再填寫本頁) ο!

Another problem is that the calculation of the control parameters uses a pre-established control model, which makes it impossible to compensate for the age variation of the control target state, the control environment, etc., and makes the paint weight inaccurate. In addition, there is no guarantee that the pre-established control model has taken into account that all fine paper sizes are applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs. Accurately improved control model. Sometimes the control model contains a large error due to the weight of the target paint. At the same time, in terms of feedback control, the useless time compensation is mainly because the attachment position from the nozzle position to the paint weight sensor is not included in Kalu. Therefore, after changing the parameters (performing the feedback control once), it is necessary to perform the feedback control again after the strip change part reaches the paint weight sensor. The accuracy improvement of coatings is also limited. In addition, if the coating weight sensor is used to scan the width direction of the strip to produce an average coating weight, it takes several tens of seconds to obtain the average coating weight, and its detection delay time is very long. On the other hand, if the representative position (such as the center) of the scanning bar is fixed, although the detection delay is short, sometimes there will be a large detection error due to the shape of the bar. [Invention Description] Therefore, one of the objects of the present invention is to overcome the shortcomings of the conventional technology and provide a control method and device to make the weight of metal paints very accurate and uniform. The above-mentioned problems are solved by the structure of the present invention described below. The hypothesis of control 値 is not equal to 眞 値 when calculating the control parameters. The solution is to provide: observe the state variation used by the control device to receive the control target at the control time, and estimate the weight of the metal coating under the control state; and The observation control device is used to modify a control parameter based on the deviation between the output of the inspection device and the weight of the target paint. When the parameter is given as the combination of the nozzle position and the gas pressure of the coating reset of the actual target, the observation control device corrects the nozzle position and the gas pressure.

Invention Description (3) to reduce deviations. A correction function calculation device is used to calculate a predetermined relationship between the gas pressure or the nozzle position for the weight of the coating, that is, the degree of change, and the correction of the nozzle position and the gas pressure parameter is made using one frame, and the line is the predetermined relationship.値 multiply by the deviation. In addition, a model error collection device is also provided to store the difference between the estimated paint weight of the control model and the positive measurement of the paint weight sensor. The problem of fixed use of the control model is solved by using This difference corrects the calculation results of both the control parameter calculation device using the control model and the observation control device. The control model has a problem of errors. The solution is to provide multiple control models and choose the control model based on the weight of the paint. The long-time useless problem of the control is solved by: using the paint heavy child sensor output and observing the device before the useless time. The output is used to compensate the output of the inspection device. The problem of the increase or inaccuracy of the detection delay time due to the operation mode of the coating weight sensor is solved by providing: a shape storage device to store the shape of the paint (according to the width direction of the strip) And the paint weight correction device, which refers to the content of the outline storage device to correct the 感应 0 induced by the paint reset sensor. The operation of the above structure of the present invention is described below. The observation device estimates the weight of the gold paint used in the current control state, and its estimated Dependants are state variables, such as those detected by the control target, such as the strip moving speed, nozzle position, and gas pressure.

The paint weight of the description of the invention (4) Check the estimated paint weight and change the control parameters to match them. Even if the paint weight cannot be measured directly, the metal to be coated in the current control state The weight of the paint is estimated and is very close to what was said at the time. The result is improved control of the accuracy of the paint weight. The control model estimates the error between the paint weight and the actual weight detected by the paint weight sensor in the previous control. It is collected in the model error collection device, and it is consistent with the weight of different paints. When calculating the control parameters, it is estimated that it is replaced by a sum (from the weight of the target paint plus or minus the difference) as the new target paint weight of the control model. In this way, the model error caused by the age variation of the control target or the control environment is corrected each time. In the calculation of the inspection device, the model error can be similarly corrected by adding or subtracting the difference of the paint weight estimated by the control model. As a result, the control parameters and observation devices can have high accuracy. Multiple control models are provided, each coating weight characteristic being almost identical. The model selected for use is reset based on the target paint, and the control parameters are calculated using the selected model. When there are multiple models to choose from, the calculation results are appropriately measured, and the data generated are used as the final parameters. As a result, each time the parameters are calculated with the most accurate model, and the accuracy of the parameters is improved. The weight of the paint that does not cause dead time is generated by the observation device. The observation error of the observation device can be calculated by subtracting the current output of the paint weight sensor from the output of the observation device before the useless time. Therefore, by subtracting the observation error from the current output of the observation device, the amount of echo can be accurately obtained without causing useless time. The implementation of back-to-performance control is the use of back-to-back performance to control the useless time compensation. 416993 (谙 First read the notes on the back and then fill out this page) ο Binding If order: Thread paper size is applicable to China National Standard (CNS) A4 (210X297 mm) _ 7-416993 Central Bureau of Standards, Ministry of Economic Affairs Industrial and consumer cooperatives print A7 B7_V. Description of the invention (5) If the paint weight sensor scans the width direction of the strip, the shape storage device stores the strip, and the average coating weight of the coating weight and shape in the width direction. The paint weight correction device first checks the part where the paint weight sensor detects the strip, and removes the paint weight 値 from the external shape storage device corresponding to the part. Subtract the average 値 from the weight of the removed paint 取出 to calculate the deviation between this part and the average 値. Finally, the skeleton deviation is used as a correction 値, and the coating reset sensor senses 値 minus the correction 値. Through the above procedure, the current shape and the current shape establish a relationship, and the relationship can eliminate the effect of Tong shape. Since the equivalent of average is calculated from the order obtained during scanning, high-accuracy paint weight can be calculated at high speed. The invention can improve the accuracy of paint reset control by providing an observation device, even if the weight of the paint cannot be detected directly. In particular, since the control gain is optimized in accordance with a change in the control amount (to be corrected for the target coating weight), stable and very accurate coating weight control can be achieved. A model error collecting device is provided, and the error information of the device is used to modify the control model, thereby eliminating the model error caused by the plant material age variation and the like. Therefore, the control parameters and the output of the observation device can be accurately obtained. According to the present invention, the feedback amount is calculated from the output of the observation device, the output before the useless time of the observation device, and the current sensing of the paint weight sensor, and the feedback The control system uses the feedback amount to execute, so it can perform very accurate dead time compensation control.

At the previous opportunity, a slice was generated that scanned a portion of the coating weight (hereinafter referred to as a portion of the coating weight). The widthwise average paint weight (hereinafter referred to as the average paint weight) is generated at the latter timing. Since the strip 151 is actually moving at the speed V, the plating paint weight detecting device 1101 scans the strip 151 obliquely.

In Walker S 10 _ 2, the paint weight deviation W is calculated from the paint weight W of the detected portion and the paint weight of 檫. Next, in steps S 1 0-3, the gas pressure correction amount ΔP is calculated from AW and the correction function Ks using Expression 5. In step S 1 0 to 4, P ·· is calculated by Expression 7. In step S 1 0 _ 5, P′Φ is used as the final gas pressure parameter, and the input device 1 0 5 is used to generate a nozzle 15 4 for the control target 150. It is determined in steps S 1 0-6 whether the average paint weight related to PΦΦ is detected. The average coating weight associated with P__ indicates the average coating weight obtained after detecting the portion of the coating weight (relevant and detected across the width direction). The calculations calculated in steps S 1 0-4 are retained until the average paint weight is derived. Steps S 1 0 — 7 are performed after the average paint reset is obtained. In steps S 1 0-7, the average paint weight is reset to W, and the target paint is reset by W ′ minus W to obtain the paint weight deviation. In addition, in step S 1 0 _ 8, the gas pressure correction set ΔP is calculated from the AW and the correction function Ks by the representative equation 5. In steps S1 0-9, the new P ... is calculated by the expression 6. In the steps S 1 0-10, P ... is used as the final gas pressure parameter, and the output device 1 5 is used to generate a 15 1 nozzle 1 5 4 for the control 檫.

Shown in Figure 12 is a paint structure diagram of the paint weight correction value 142. The currently generated coating weight and the distance from the end of the strip during the reset detection of the coating are received from the plating coating weight detection device 1101 via the input device 102. After that, both the average paint weight Wue-prev and the previous part paint weight W tenip-prev of the part related to the same distance from the end of the strip are taken out from the external storage device 140. TempAWmod subtracted from Wtemp-prev is used as the correction 値, and 値 Wfiltered obtained from Wtemp-AWmod is used as the paint weight return to the control device 1102. According to this embodiment, since the variation in the weight of a portion of the coating depending on the location to be detected can be corrected by the shape obtained from the last scan, a signal equal to the average coating weight can be used as a return signal. As a result, the accuracy of the feedback control with a portion of the coating weight before the average radon is obtained is improved.
