直流调速系统中常规PI与模糊PI控制器的比较

摘要

转速电流双闭环直流调速系统中的PI控制器直接影响其调速性能,利用MATLAB分别建立了由常规PI与模糊PI控制器组成的转速电流双闭环控制直流调速系统的仿真模型,并进行了仿真.仿真结果表明,模糊PI控制器与常规PI控制器相比具有更好的动态稳定性和跟踪性能,对外界干扰具有较强的鲁棒性.%The PI controller directly affects the speed regulating performance of the speed DC drive current double closed-loop system, the paper makes use of MATLAB to built two speed DC drive current double closed-loop control system simulation models respectively, one of them consists of conventional PI controller and the other one consists of fuzzy PI controller, and the line of the simulation. Simulation results show that the fuzzy PI controller is superior to the conventional PI controller in dynamic stability performance and speed tracking power, and the fuzzy PI controller has strong robustness to external disturbance.
