摘要:

对于双闭环直流可逆调速系统，提出了一种将模糊控制与常规PI控制相结合应用在转速环调节器设计的方法。根据工程经验与专家知识所确定的模糊控制规则，进行模糊推理，实现转速环调节器参数的动态整定。应用Matlab软件构建了双闭环直流可逆调速系统的仿真模型，并对转速环分别采用模糊PI控制器和常规PI控制器的直流可逆调速系统分别进行仿真实验并对比结果。从仿真结果可以得出采用模糊控制可以对直流可逆调速系统的动态与静态特性、抗扰性能、恢复性能以及跟踪性能有比较明显的改善与提高。

Abstract:

For the double closed-loop DC reversible speed control system, a method combining fuzzy control with conventional PI control is proposed on the design of speed-loop regulator. According to the engineering rules and expertise knowledge to determine the rules of fuzzy control, The parameters of speed-loop regulator can achieve dynamic tuning based on fuzzy reasoning. The simulation model of double closed-loop DC reversible speed control system is constructed by Matlab software, and the simulation of DC reversible speed regulation system with fuzzy PI controller and conventional PI controller are compared respectively. The simulation results have shown that fuzzy control can obviously improve the dynamic and static characteristics, anti-disturbance performance, recovery performance, and tracking performance of DC reversible speed control system.
