自适应模糊PID控制器的设计

Design of Self-Adaptive Fuzzy PID Controller

目前的工业过程控制中被控对象往往都是非线性、时变的系统,常规PID控制对于这样系统的控制效果不是很理想。为此,提出将模糊技术与PID控制相结合的控制方式,设计出自适应模糊PID控制器。利用Matlab中模糊逻辑控制工具箱设计模糊控制器,在Simulink环境中实现了该自适应模糊PID控制器的仿真。仿真结果表明,该模糊PID控制具有控制灵活、响应快和适应性能强的优点。

At present,the control object in industrial processing control is time-varing nonlinear system.The conventional PID controller is not usually applicable to the type of systems.So a new fuzzy adaptive PID controller is presented using a fuzzy logic control toolbox in Matlab to design the fuzzy controller,and constructing the PID control system in Simulink environment,the computer simulation of this adaptive fuzzy PID controller is realized.Simulation results show the fuzzy PID control has advantages of flexi...
