摘要：
The PMSM drive system contains the continuous state variables and the discrete variables, which is a typical hybrid system. In this paper, the hybrid system theory is introduced into the analysis process, and the discrete voltage model of the inverter is embedded into the continuous state equation of the motor, and the hybrid logic dynamic model of the motor drive system is established. Based on this, a new control method of permanent magnet synchronous motor without current sensor is proposed, and the validity and reliability of the proposed control method are proved by MATLAB/Simulink simulation.
