Abstract As the speed will be greatly influenced by the variation of load in permanent magnet synchronous motor (PMSM) vehicle driving system, a two-order active disturbance rejection controller (ADRC) speed control system based on load observer is designed. The control system is combined with ADRC to observe and compensate load disturbance, which can suppress external disturbance. The control equation of ADRC governing system with load observer is deduced, and the load observe control volume is established as the compensation input of speed loop. Besides, it is compared with ADRC system without load disturbance. Simulation and experimental results show that ADRC governing system with load observer has stronger ability of anti-interference, and the dynamic performance and the response performance of PMSM frequency control system have improved. ADRC control system with load observer can better satisfy the control requirements of electric vehicle.

Key words： Permanent magnet synchronous motor load observer active disturbance rejection controller speed modulation system
