基于模糊PID控制的海洋绞车排缆系统

Marine Winch Cable Arrangement System Based on Fuzzy PID Control

海洋绞车排缆控制系统易受负载扰动、系统参数变化等不确定因素的影响,且常规PID(Proportion-Integral-Derivative)控制器的抗干扰能力较差、排缆精度较低,由此,设计基于模糊PID控制的海缆绞车排缆系统。从理论上分析海洋绞车排缆系统的工作机理,详细阐述模糊控制算法并设计模糊PID控制器。在MATLAB/SIMULINK软件中依据矢量控制和SVPWM调制原理建立排缆控制系统模型。对建立的模型进行仿真,并将其与常规PID控制系统相对比。仿真结果表明,所设计的系统具有响应快、超调量小和抗干扰能力强等优点,能较好地满足排缆控制系统的性能要求。

The sophisticated operating condition of marine winches makes the cable arrangement control system susceptible to the unpredictable factors such as load disturbances and variation of system parameters,and the poor anti-jamming capability and low cable arrangement accuracy of the conventional PID(Proportion-Integral-Derivative)controller also affect the operation.Therefore,this study proposes a winch cable arrangement system based on fuzzy PID control.The working mechanism of the marine winch cable arrangement system is theoretically analyzed,the fuzzy control algorithm is elaborated and a fuzzy PID controller is designed.Then,a winch cable arrangement system model is established in Matlab/simulink based on vector control and SVPWM modulation principle,which was simulated and compared with the conventional PID control system.The simulation results show that the system designed has the advantages of fast response,small overshoot and strong anti-interference ability.It can satisfy the performance requirements of the winch cable arrangement control system.
