摘要:

针对两相静止坐标系下基于观测器进行IPMSM无传感器控制时存在电角度估算误差与交直轴电感和负载转矩耦合、电角度补偿复杂等问题,文中选择在同步旋转坐标系下采用电机原有电感参数进行IPMSM无传感器控制。通过建立PMSM 的矢量数学模型,对存在电角度估算误差时采用IPMSM原参数对反电动势估算的影响进行分析,分析结果验证了该方法的理论可行性。利用MATLSB/Simulink进行仿真,并进行了针对性实验。实验结果表明,文中所提算法无须电角度补偿,在扰动条件下仍能对电机转子位置和速度进行良好地跟踪。

Abstract:

For the sensorless control of the IPMSM based on the observer in the two-phase stationary coordinate system, thereare problems including coupling of electrical angle estimation error, the cross-axis inductance and load torque, and complicated electrical angle compensation. In order to solve these problems,the sensorless control of IPMSM was carried out by using the original inductance parameters of the motor in the synchronous rotating coordinate system in this study. By establishing the vector mathematical model of PMSM, the influence of the original parameters of IPMSM on the estimation of back EMF was analyzed when the electrical angle estimation error existed. The conclusion of the method verified the theoretical feasibility of the method. The simulation was conducted by MATTSB/Simulink, and the targeted experiments were performed. The results showed that the proposed algorithm did not require electrical angle compensation, and could track the rotor position and speed of the motor under the disturbance condition.

Key words: interior permanent magnet synchronous motor, disturbanceobserver, sensorlesscontrol, phase-locked loop, synchronous rotating coordinate system, vector control.
