摘要
基于PID控制与模糊控制各自的优点,将模糊控制与常规PID控制相结合,并运用变论域的方法,设计了变论域自适应模糊PID控制器.然后,以直流电机为模型,实现对其转速的控制,使用Matlab进行可行性研究,并将其仿真结果与PID控制和模糊控制的仿真结果进行比较.结果表明,基于直流电机的变论域自适应模糊PID控制器的控制效果明显优于常规PID控制和模糊控制.
Fuzzy control and conventional PID control were combined in this paper;meanwhile,the method of variable universe was adopted.In this paper,a variable-universe and self-adaptive fuzzy PID controller was designed and utilized in a DC motor model to achieve the speed control of the DC motor.This paper used the tool of Matlab to complete this system＇s feasibility study and compared the simulation results with the PID control and fuzzy control＇s simulation results.The results showed that the control performance of the variable-universe and self-adaptive fuzzy PID controller was obviously better than PID control and fuzzy control.
