基于模糊逻辑的反环绕补偿设计

Anti-windup Compensation Design Based on Fuzzy Logic

针对控制系统中由于存在限幅而产生的环绕现象,提出了基于模糊逻辑的抗环绕补偿器设计方法.对所设计的模糊补偿器和传统的基于反计算思想及基于条件作用技术的补偿器进行了仿真,仿真结果表明所提出的模糊方法与传统的反环绕方法及基于条件作用技术相比,具有更好的跟踪性能,且所设计的模糊补偿器结构简单,易于实现.

In view of the windup problem existing in control system with limiting,a kind of fuzzy logic-based compensation method is proposed.The designed fuzzy compensator and conventional compensator based on back-calculation and conditioning technique are simulated.Simulation results show that the proposed fuzzy method gives generally better tracking performances than the back-calculation and conditioning technique.The designed fuzzy compensator has advantages of simple structure and is easy to realize.
