Research on Pump Speed Control System Based on Fuzzy PID

In this paper, based on Matlab/simulink, the PID vector frequency conversion control of permanent magnet synchronous motor has better drive control performance in the multi-stage centrifugal pump speed control system. The electric-hydraulic coupling system of centrifugal pump has a good evaluation and research function. In view of the low efficiency of the traditional PID control method and the poor adaptability to the change of working environment, a vector control method of permanent magnet synchronous motor based on adaptive and self-adjusting fuzzy control principle is proposed for the speed regulation system of water pump. The simulation results show that the PMSM system con-trolled by the fuzzy PID controller is superior to the tradi-tional PID control, and has better disturbance resistance, dy-namic and steady performance.
