The traditional permanent magnet synchronous motor (PMSM) control system uses a mechanical sensor to detect the speed of the motor and the position of the rotor，the sensor is susceptible to the environment and reduces the reliability of the system.This paper uses a model reference adaptive system (MRAS) instead of a mechanical sensor to estimate the speed of the motor and the position of the rotor.Taking the mathematical model of the three-phase permanent magnet synchronous motor as a reference model,taking the motor speed as the identification parameter to establish an adjustable model,the reference adaptive law is determined according to Popov's hyperstability theorem.The speed controller of the control system adopts sliding mode control (SMC) based on integral sliding surface and exponential reaching law.The simulation results show that the sliding speed control system based on MRAS for permanent magnet synchronous motor can realize the estimation of the motor speed and rotor position, which can guarantee the good dynamic quality of the speed control system.
