[Abstract]:Permanent magnet synchronous motor (PMSM) is widely used in various fields because of its excellent performance and simple structure. In the process of closed-loop control of permanent magnet motor, it is necessary to know the rotor position of the motor. In order to reduce the cost and improve the reliability, the switch Hall position sensor is used to detect the rotor position. Because of the low resolution of the sensor, it is necessary to linearize the Hall position signal. Position sensorless control has been greatly developed, but the surface permanent magnet synchronous motor is a hidden pole motor, which is difficult in zero speed and low speed sensorless control. In this paper, the control of low-cost permanent magnet synchronous motor (PMSM) is studied. In this paper, the self-learning of the offset angle of the switch hall position sensor with three-phase symmetrical installation is realized. On this basis, the rotor position obtained by Hall position sensor is controlled by magnetic field orientation. The zero order algorithm and the first order algorithm are used to linearize the discrete switched Hall signal. In order to further optimize the rotor position, the observer is used to correct the angle. The experimental results show that the sinusoidal degree of winding current is improved and the current THD decreases from 2.73% to 1.61g under rated load. By comparing the starting performance of the motor with three control algorithms, it is found that the starting torque of the motor is the largest in the square wave starting mode. The control method of sensorless position sensor is studied as the control method of position sensor fault. When the speed of motor is zero speed or low speed, the rotor position of permanent magnet synchronous motor (PMSM) is estimated by pulse voltage injection method. Based on the error processing algorithm using PLL, robust observer is used to improve the algorithm. The robust observer coefficient is determined by mathematical derivation and calculation. The algorithm is verified by simulation and experiment. The convergence time of the observer method is significantly shorter than that of the phase-locked loop algorithm, from 0.5 s to 10 Ms. When the motor is running at medium and high speed, the rotor position is estimated by sliding mode observer. The sliding mode plane is designed by combining the sliding mode theory with the mathematical model of the motor. The algorithm is verified by simulation and tested on the experimental platform. The experimental results of the above algorithms are satisfactory.
