摘要: 针对矿用电机车永磁同步电动机调速采用无传感器控制时存在转子位置角估计精度低、计算量大、稳定性和抗扰动性差等问题，提出了一种改进模型参考自适应法。该方法根据直轴电流为零简化自适应律，降低计算复杂程度；采用滑模控制器替代PI调节器来控制转速环，减少扰动影响。仿真和试验结果表明，该方法能准确估计转子位置角，减小转速波动，具有很好的稳定性和抗扰动能力。Abstract: In view of problems of low accuracy of rotor position angle estimation, large computation, poor stability and anti-disturbance performance when sensorless control was used in speed regulation of permanent magnet synchronous motor of mine-used electric locomotive, an improved model reference adaptive system was proposed. Adaptive law is simplified according to zero direct axis current, so as to reduce complexity of calculation. Sliding mode controller is used instead of PI regulator to control speed loop, so as to reduce disturbance influence. The simulation and experimental results show that the method can accurately estimate rotor position angle, reduce speed fluctuation, and has good stability and anti-disturbance ability.
