粘着控制实验平台中的交流永磁同步电机

he mathematical model of permanent magnet synchronous motor (PMSM) under d-q axis is introduced. A method with a strong engineering value of PMSM parameters identification is presented. The stator resistance and direct inductance are detected using step response test of direct current, quadrature inductance is measured by applying pulse voltage to PMSM, rotor flux is identified under speed driven condition. Based on vector control, speed control system of permanent magnet synchronous motor is designed, including the design of current loop and speed loop. Do experiments on TMS320F2812 DSP-based adhesion control platform. The experimental results show that parameter identification method is feasible and speed control system has good dynamic and static performance.
