多模态模糊PID控制算法在转台伺服系统中的应用

Multi-Mode Fuzzy PID Control Algorithm Application in Table Servo System

由于结构简单,可靠和安全,PID控制广泛用于伺服控制系统。但其固有的缺陷导致对复杂系统控制效果变差。为解决某些问题,设计一种多模态模糊PID控制器,应用模糊控制理论在线调节控制器参数和结构。通过控制实际转台伺服系统验证其具有良好的控制效果。

The PID control is widely used in servo systems as it has simple structure,reliability and safety.However,it has certain problem in a complex system,resulting in imperfect performance.To solve some problem,a new multi mode fuzzy PID controller is proposed in this paper,which on-line tuning the parameters and modifying the structure of controller based on fuzzy control theory.The good performance and advantage is verified through experiments and results after controlling platform servo system.
