Abstract

PURPOSE:To reduce the time required for regulating a new object to be regulated by using the regulated result of a past similar or coincident regulator example as the initial value of new regulating at the time of performing the new regulation. CONSTITUTION:A retrieving section 2 retrieves the regulated results of past coincident or similar regulated example having the same regulating condition as that of a new object to be regulated from a regulated result storing memory area 1 by using the regulating condition of the new object to be regulated as a key. A comparing section 3 selected the most approximate regulated example by comparing the retrieved results of the section 2 with the regulating condition of a machine 5 which is the new object to be regulated and gives the regulated result of the selected regulated example to a regulating section 4. The section 4 regulates the machine 5 by using the regulated result given from the section 3 as an initial valve. Therefore, the time required for regulating the new object to be regulated can be shortened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjusting device for adjusting an electric motor driving device for controlling the speed of an electric motor to a predetermined value.

[0002]

2. Description of the Related Art FIG. 3 shows an electric motor (7-1, ... 7-k-
1,7-k + 1) electric motor drive device (6
It is a figure which shows the mode of adjustment using the conventional adjusting device 9 of -1, ... 6-k-1, 6-k + 1). In this figure, 1
The figure shows a situation in which adjustment is started in order from the electric motor drive device that is the second adjustment target, and the k-th electric motor drive device is being adjusted. Although it is not shown in the figure, the past adjustment results were not stored in the conventional adjustment device.Therefore, when making individual adjustments, an arbitrary initial value or an appropriately set specified value was always used. Was used.

[0003]

In the above adjustment work,
Even when adjusting many motor drives of the same type to the same specifications, the adjustment is always started using an arbitrary initial value or an appropriately defined specified value. However, there was a problem that it took about the same amount of time.

In order to eliminate the above problems in the prior art, the present invention makes a new adjustment close to the final result of the new adjustment from the past adjustment results or the same data.
It is an object of the present invention to provide an adjusting device that can shorten the adjusting time by using the parameter as an initial value.

[0005]

In order to achieve the above object, when a plurality of adjustment targets are adjusted, a storage device for storing a plurality of past adjustment records is provided, which is necessary for the adjustment of a new adjustment target. Based on the constants and the adjustment specification for the adjustment target, the stored content of the stored value is searched, and a means for searching and extracting an adjustment record that is the same as or similar to the constants and the adjustment specification is provided. When adjusting the adjustment target,
The result of the extracted adjustment recording is used as an initial value of a new adjustment.

[0006]

[Operation] In the adjusting device for adjusting a plurality of objects to be adjusted,
The constants necessary for the adjustment of the new adjustment target and some or all of the adjustment specifications for the adjustment target may be similar to or the same as cases in which adjustment has been performed in the past. In this case, it is highly likely that the adjustment result of the new adjustment target is similar to or coincides with the adjustment result of the case. Therefore,
In this case, by using the adjustment result of the past similar or matching adjustment cases as the initial value in the new adjustment, quick adjustment is possible.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an adjusting device according to an embodiment of the present invention. In the figure, 1 is an adjustment result storage memory area. For each individual adjustment result in the past, the adjustment conditions of the adjustment target, that is, the constants necessary for the adjustment, the adjustment specification for the adjustment target, and the adjustment result satisfying the adjustment specification are stored as a pair. Keep it. Attributes such as the date and time, the place, the name of the coordinator, and the keyword when the adjustment was made may be stored together.

The retrieving unit 2 retrieves the adjustment result storage memory area 1 by using the adjustment condition of the new adjustment object as a key,
A case of a past adjustment result that is the same as or similar to the adjustment condition of the new adjustment target is searched. The number of search results may be plural.

The comparing unit 3 compares the plurality of search results with the adjustment condition of the device to be adjusted newly to be adjusted from among the plurality of search results searched by the search unit 2, and finds the closest degree of approximation. Select adjustment cases with high The comparison unit 3 gives the adjustment result of the adjustment case to the adjustment unit 4.

The adjusting section 4 adjusts the machine to be adjusted 5 by using the adjustment result given by the comparing section 3 as an initial value. Adjustment unit 4
Is provided with an input unit 41, and the coordinator inputs the adjusted securities. The adjustment condition may be transferred to the input unit 41 by data transfer from the host computer. This adjustment condition is sent to the search unit 3 as a search key. After the adjustment is completed, the adjusting section 4 pairs the adjustment condition and the adjustment result and transfers them to the adjustment result storage memory area 1.

FIG. 2 is a block diagram when the present invention is applied to an adjusting device for adjusting an electric motor drive device for controlling the speed of the electric motor to a predetermined value. In FIG.
The same components as those in FIG.

In the present embodiment, the adjustment of the speed control system when the electric motor drive device 6 drives the electric motor 7 will be described as an example. The electric motor drive device 6 includes a control unit 62 that controls a variable power supply 61 that drives the electric motor 7. A speed detector 8 is attached to the electric motor 7, and the detected electric motor speed is fed back to the control unit 62.

In this embodiment, the adjusting unit 4 adjusts the control constants related to the speed control of the control unit 62. Equation (1) shows an example of the data structure of the adjustment conditions. (Motor model number, step response settling time, step response overshoot allowable value) (1) These data (adjustment conditions) are the same as those in the first embodiment. Input from 41 by the coordinator. The adjustment conditions are
The data may be transferred from the upper computer to the input section 41 by data transfer. Expression (2) shows an example of the configuration of the adjustment result.

(Proportional Gain, Integral Gain) (2) In this example, proportional / integral is used as the control logic of speed control, so the data of the adjustment result is proportional / integral 2 It consists of two gains. As the control logic of speed control,
When a logic other than proportional / integral is used, or when an additional compensating element is used in addition to proportional / integral, the data structure corresponds to each of them. After the adjustment is completed, the adjusting unit 4 pairs the adjustment condition and the adjustment result with each other and transfers them to the adjustment result storage memory area 1 as in the first embodiment.

[0015]

As described above, according to the present invention, when a new adjustment is performed, a case having a similar or the same adjustment condition is searched from past adjustment cases, and the adjustment result in the case is retrieved. Since it is used as the initial value in new adjustment, there is an effect that the time required for new adjustment can be greatly reduced.
