Interior Permanent Magnet Synchronous Motor (IPMSM) significantly speed fluctuations under load change suddenly conditions. With the help of MATLAB/Simulink simulation software, a novel IPMSM speed loop control strategy is studied. A Fuzzy linear active disturbance rejection (Fuzzy-LADRC) speed controller is designed, and the LADRC parameters are dynamically adjusted by Fuzzy control to reduce the speed fluctuations of IPMSM in this paper. Finally, the dSPACE experimental platform is used to conduct simulations and experiments. The simulation and experimental results show that the Fuzzy-LADRC has stronger anti-disturbance than the conventional LADRC controlled IPMSM drive system, and the motor speed fluctuations are small.
