针对目前设计模糊规则表采用的启发式方法具有设计周期长、过分依赖设计者的经验和技术知识等缺点,介绍一种模型参考初始化设置的设计方法.它简单,易于计算机实现,可以实现模糊规则表的自动初始化设置.Matlab仿真结果表明,基于模型参考初始化设置的模糊控制可使天线伺服系统的动态性和稳定性都明显优于传统PID和用启发式方法设计的模糊控制.最后,针对将模型参考初始化设置方法设计的控制器应用到实际系统中存在稳态误差的问题,运用PID和模糊控制的复合控制方法,有效地消除了稳态误差.%The heuristic method which is used to design the fuzzy rule table costs too much time and depends too much on the designer's experience and technical knowledge. This paper introduces a method of model reference initialization. It is simple and easy to implement by computer, and the automated initialization of fuzzy rule table can be realized. The simulation result of Matlab shows that, compared with the control based on PID and heuristic method, the dynamic and stability of the fuzzy control based on model reference initialization are remarkably improved. At last, it's found that when the fuzzy controller based on model reference initialization is used in actual system, the steady-state error exists. In this paper the combined control method of PID and fuzzy control is proposed to eliminate the steady-state error effectively.
