[0006] The disadvantage of the above deviation signal decomposition is: the first type of method directly distributes the deviation signal to different scale controllers, so the small-scale actuator A1 will cause excessive action in the case of deviation, and the large-scale actuator A2 will move frequently in the case of small deviation; the second In the second method, the deviation signal is divided by the threshold d, and the small-scale actuator does not participate in the control before the deviation signal is smaller than the threshold, so the transition time of the control system is longer, which is the sum of the transition time of each scale control system

Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] Such as figure 1 , the invention provides a system block diagram of a method for realizing multi-scale control by multiple actuators. This method decomposes the deviation signal into deviation signals of different scales synchronously, and distributes them to controllers and actuators of corresponding scales, so as to realize the purpose of joint control of multiple actuators. Specific steps are as follows:
[0034] S1. Comparing the actual process parameter y obtained under the control of the actuator with the target value parameter y* controlled by the actuator to obtain the deviation signal e;
[0035] S2. The deviation signal e passes through the deviation decomposition unit D 1...

The invention discloses a variable scale control method for multiple execution mechanisms, relating to the industrial control field. The working flow of the control system comprises steps of comparing the current process parameter with a set goal to obtain a difference signal, splitting a deviation signal into a plurality of different deviation signals through a deviation decomposition unit, and transmitting the split deviation signal to a corresponding controller to obtain a corresponding control signal, wherein the control signal enters a control object after going through a corresponding execution mechanism and a new cycle of process parameters is generated. The invention avoids the excessive motion and frequent motion of the execution mechanism and saves the control time.
Description
technical field [0001] The invention relates to the field of industrial control, in particular to a scale-variable control method of multiple actuators. Background technique [0002] Because the execution structure cannot take into account both the adjustment range and the adjustment accuracy, multiple actuators with different accuracy are generally used in the industry to control the same process parameter. [0003] The key to multi-actuator control of the same process parameter lies in the way of distribution of deviation signals, which is usually achieved by direct distribution or threshold comparison in the industry. Such as figure 1 Shown is a block diagram of the control system with 2 actuators. The working process of this control system is as follows: (1) Compare the actual process parameter y obtained under the control of the actuator with the target value parameter y* to be obtained under the control of the actuator to obtain the deviation signal e; (2) The deviat...
