Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment party
Formula and accompanying drawing, be described in further details the present invention.Here, the exemplary embodiment of the present invention
And explanation is used for explaining the present invention, but not as a limitation of the invention.
Why fluctuation ratio is relatively big in view of current control mode for inventor, mainly uses single
Desired value, it is desirable to rely on the control mode settled at one go to realize controlled parameter and reach desired value.If can
So that desired value to be divided into several stage realize, i.e. arrange multiple intermediate value, elapse a step according to the time
Step approaches final desired value, and controlling process the most comparatively speaking can be the most steady.
Based on this, in embodiments of the present invention, it is provided that a kind of apparatus control method, as in figure 2 it is shown,
Comprise the following steps:
Step 201: obtain the desired value of controlled parameter；
That is, determine and need to be transferred to controlled parameter what kind of value, such as, if controlled device
It is air-conditioning, it is now desired to the temperature of air-conditioning is adjusted to 26 DEG C, then controlled device is exactly air-conditioning, is subject to
Control parameter is exactly temperature, and desired value is exactly 26 DEG C.
Step 202: according to described desired value be controlled device generate multiple intermediate values；
After knowing that desired value is 26 DEG C, if current temperature is 10 DEG C, then adjust at this
During whole, be equivalent to the temperature difference having 16 DEG C, if directly increasing to 26 DEG C, it is clear that span is too big,
Needing the biggest output, corresponding follow-up readjustment also can be more complicated.
To this end, can realize stage by stage, i.e. can generate many according to the concrete situation that controls of controlled device
Individual intermediate value, for example, it is possible to generate centre according to the mode constituting arithmetic progression between multiple intermediate values
Value, such as, can generate 3 intermediate values, 14 DEG C, 18 DEG C, 22 DEG C, then use Step wise approximation
Mode control that controlled parameter reaches final 26 degrees Celsius, i.e. first control temperature by 10 DEG C of risings
To 14 DEG C, then control temperature and risen to 18 DEG C by 14 DEG C, control temperature the most again and risen to by 18 DEG C
22 DEG C, control temperature the most again and risen to 26 DEG C by 22 DEG C.
The mode of above-mentioned arithmetic progression is only a kind of mode generating intermediate value, it is also possible to use other
Mode, for example, it is contemplated that it is the biggest to arrange intermediate value to early stage, after be gradually reduced adjustment amplitude,
That is, the mode being gradually reduced according to the difference between multiple intermediate values generates multiple intermediate value, because finishing
Unexpectedly the intermediate value distance final goal value of early stage is distant.Such as, it is still 26 DEG C with desired value, when
Front temperature illustrates as a example by being 10 DEG C, and can arrange intermediate value is 17 DEG C, 23 DEG C, i.e. first
Temperature is increased to 17 DEG C by 10 DEG C, the most again temperature is increased to 23 DEG C by 17 DEG C, finally by temperature
Degree is increased to 26 DEG C by 23 DEG C.
Step 203: the controlled parameter controlling described controlled device is progressively forced according to the plurality of intermediate value
Nearly described desired value.
In this step, controlled device can be controlled and first arrive first intermediate value, then determine by
After control equipment is stably in first intermediate value, just controls controlled device and reach second centre
Value, after determining that controlled device is stably in second intermediate value, just controls controlled device and reaches
3rd intermediate value, by that analogy, until controlled device is stably in desired value, wherein, first
Difference between individual intermediate value and described desired value is more than described second intermediate value and described desired value
Between difference, i.e. intermediate value is gradually to approach final desired value.
In upper example, by optimizing the desired value setting means of controlled parameter of robot control system(RCS), according to by
The mode gradually approached arranges desired value, such that it is able to realize the control of fast and stable, decreases and started
Journey do not mates caused loss.
In conjunction with a specific embodiment, the said equipment control method is illustrated, however noticeable
It is that this specific embodiment is merely to be better described the present invention, and be not intended that the present invention is improper
Limit.
In this example, the desired value of controlled parameter not according to single set-point, but during the course by
Gradually adjust, gradually approach.
As shown in Figure 3 and Figure 4, desired value 1, desired value 2, desired value 3 ... be suitable according to the time
Sequence is sequentially adjusted in, and first provides desired value 1, and the controlled parameter of robot control system(RCS) first reaches desired value 1,
Adjusting desired value according to actual control situation is desired value 2, then adjusts according to actual control situation
Whole desired value is desired value 3, by that analogy, until being finally reached desired value.
The robot control system(RCS) worked in this manner, can avoid exporting significantly beyond demand as far as possible
Situation, therefore controls process more steady, can be prevented effectively from fluctuation, can also effectively reduce simultaneously
Loss when exporting excessive.
Specifically, the given way of above-mentioned desired value can select the most flexibly, so long as not pressing
According to single control desired value, but the control mode of the requirement being finally reached desired value by adjustment is equal
It is included in the protection domain of the application, for example, it is possible in determining according to a predetermined computing formula
Between be worth, or approach according to certain formula, or the mode manually adjusting intermediate value can.
Based on same inventive concept, the embodiment of the present invention additionally provides a kind of plant control unit, as
Described in the following examples.Owing to plant control unit solves principle and the apparatus control method phase of problem
Seemingly, therefore the enforcement of plant control unit may refer to the enforcement of apparatus control method, in place of repetition not
Repeat again.Used below, term " unit " or " module " can realize predetermined function
Software and/or the combination of hardware.Although the device described by following example preferably comes real with software
Existing, but hardware, or the realization of the combination of software and hardware also may and be contemplated.Fig. 4
