用模糊控制自整定PID参数的研究

Study on PID parameter self-tuning by using fuzzy control

针对复杂的非线性时变系统,研究了将模糊系统与普通PID相结合的自适应模糊PID控制系统,总结了该控制器的设计过程及设计方法。仿真结果表明,这种控制器是一种易于理解、便于实现、性能良好的控制器,能适用于非线性、时变、较强干扰的复杂系统。

The adaptive fuzzy PID control system which combines the fuzzy system with ordinary PID is studied for the complex nonlinear time-varying system. The design process and method of the controller are summed up. The simulation results show that the controller is easy to understand and easy to implement, has good performance, and can be applied to nonlinear, time-varying and strong anti-interference complex systems.
