Problems solved by technology

[0006] Although the repetitive compensation control can guarantee the output accuracy to track the given value, it has two disadvantages: figure 1 It can be seen that the control command obtained by repeated compensation is not output immediately, but is output after a reference cycle lag
[0007] It can be seen that the existing repetitive compensation PID control scheme will increase the debugging time of the servo control system stabilization loop

Embodiment Construction

[0036] Aiming at the shortcomings of conventional PID control method for DC servo system, long adjustment period of parameters and difficulty in improving system accuracy, the present invention proposes a PID control scheme based on repetitive compensation. This scheme improves on the repetitive compensation control structure. The improved control scheme not only guarantees the system performance index, but also shortens the parameter adjustment cycle and improves the accuracy of the system to isolate disturbances.

[0037] The control scheme provided by the invention has a relatively good application prospect in the seeker optical cabin. In this embodiment, the DC motor of a certain optical cabin is used as the control object, such as figure 2 As shown, the system uses gyro-sensitive control object's current position for feedback. The input of the PID controller is the difference between the given amount r and the feedback amount y of the control object, and the difference...

Abstract

The invention discloses an improved repeated compensation PID control system. A second PID controller is serially connected to a branch where a time delay link of a repeated compensation PID controller. The PID parameter of the second PID controller is the same as that of the PID controller, and the second PID controller is arranged before the time delay link. The invention also discloses a construction method of the system. The method comprises steps of firstly adjusting system parameters on the basis of not adding the second PID controller; then, adding the second PID controller, where the PID parameters of the second PID controller does not need to be adjusted; and using the parameter of the PID controller on the main branch. According to the invention, by optimizing the parameters of the servo system, the effects on the control system imposed by the system time delay are reduced and the debugging time of a stabilizing loop of the servo control system will not be increased.

Description

technical field [0001] The invention relates to the technical field of PID control, in particular to a method for improving the control performance of a repetitive compensation PID control system. Background technique [0002] Many seeker optical cabins use DC servo systems, which require fast tracking input commands without overshoot, high control loop performance indicators, and strong anti-disturbance capabilities, etc., which put forward higher requirements for DC servo systems. DC servo systems have a structure It has the advantages of simplicity, light weight, large starting torque, wide speed range, easy control, and convenient maintenance, etc., and has been widely used in the seeker optical cabin. [0003] Conventional PID controllers have been widely used because of their simple structure, no need for precise mathematical models of objects, easy operation, and wide applicability, but they have poor robustness, low control accuracy, and poor adaptability. In the sy...
