Design of Self-adaptive Fuzzy PID Control System and its Computer Simulation

提出了一种参数自适应模糊PID控制器,将模糊控制器和PID控制器结合在一起,利用模糊逻辑控制,并把MATLAB中的Fuzzy Toolbox和SIMULINK有机结合起来,实现了PID控制器参数在线自调整。进一步完善了PID控制器的性能,提高了系统的控制精度。仿真结果表明:该控制器明显改善了控制系统的动态性能,参数自适应模糊PID控制器能使系统达到满意的控制效果,对进一步应用研究具有很好的参考价值。

In this paper,a kind of parameter self-adaptive fuzzy PID control system is discussed,it uses Fuzzy logic controller which is combined with PID controller and the organic combination of Fuzzy Toolbox and SIMULINK that makes the parameter＇s self-adaption of PID controller possible. It perfects the properties of PID controller and improves the precision of control system. The result of simulation indicated that the controller improved the dynamic property,the self-adaptive fuzzy PID control system gives a good control performance and has a high reference value for further applications.
