一种实用的变参数PID控制

A Method of Variable Parameter PID Control

由于模拟随动系统存在算法呆板、电路调试繁琐等不足之处,数字控制系统应运而生。PID控制因为结构简单、稳定性好、可靠性高等优点被广泛应用。实际控制系统往往存在非线性因素,常规PID不能满足实际需求。根据某型号图像导引头稳定伺服控制系统设计应用情况,提出了一种简单实用的变参数PID控制方法。经试验测试验证该方法稳定可靠,能够满足系统要求。

Digital control system comes forth owing to cut-and-dry arithmetic and difficult debugging of analog system.PID control is applied broadly because of simple structure,stability and reliability.In application,General PID control can＇t satisfy system needs due to nonlinearity.A sort of simple and applied PID control method is put forward based on the specific image seeker stabilization-servo system and is testified to be true of the system.
