Based on the mathematical model of permanent magnet synchronous motor(PMSM),closed form expressions for speed and current PI controller parameters was deduced.The principle of field oriented control was analyzed,and the measurement method of PMSM parameters was derived based on the mathematical model.The PI parameter tuning method of traditional control algorithm was given,and the PI parameter setting method based on IMC strategy,introducing new parameters to optimize control and combining with the actual motor parameter measurement method.The closed-loop parameter design process of permanent magnet synchronous motor was simplified,and a new parameter setting formula was derived.At the same time,the simulation model of PMSM field oriented control system and the STM32 hardware platform were built.The experimental results show that the correctness of motor measurement parameters and PI parameters tuning in this thesis have favorable dynamic performance and anti-disturbance capability.This method has guiding significance for adjusting parameters of actual motor.
