变负载随动系统的新型控制方法研究

New Control Methods for Servo-System with Time-Variety Load

变负载的随动系统在自动化武器装备领域中应用日益广泛,然而常规的PID控制器不能满足变负载情况下的高精度要求。为实现变负载条件下的高精度随动控制,提出运用两种新型控制方法,即自适应逆控制和自抗扰控制器。自适应逆控制和自抗扰控制器控制思想新颖,应用在随动系统的速度环控制中,对系统的内扰和外扰有良好的消除和抑制作用。通过仿真研究表明,与常规PID控制器相比,自适应逆控制和自抗扰控制器对随动系统速度环的变负载控制的性能良好,是实现高性能的变负载随动系统的有效方法。

Servo - systems with time - variety load are used in automatic weapons very broadly, but general PID controller is not able to approach high performance in condition of time - variety load. To approach high performance, two new methods are introduced and used, which are Adaptive Inverse Control （AIC） and Active Disturbance Rejection Control （ADRC）. AIC and ADRC have new control ideas, and are able to eliminate or reduce the effect of internal and external disturbance of the plant, which can be used in controlling speed - loop of servo - systems with time - variety load. Simulation suggests that AIC and ADRC have better performance controlling speed - loop of servo - systems with time- variety load than general PID controller, so they are very efficient methods for approaching high performance.
