| 中文摘要 |
| 针对内嵌式永磁同步电机无位置传感器控制系统, 基于自抗扰控制技术和高频信号注入技术, 提出了以转子位置角为扩张状态观测器(extended state observer, ESO)主体变量的自抗扰控制系统. 该方法避免了传统算法中以电流为ESO主体变量时依靠角速度估计值积分来获得转子位置角估计值所带来的误差积累问题. 该方法在电机起动、负载突变等电流波形正弦度较差的情况下, 仍能保证转子位置角的估计值具有较高的精度. 仿真结果验证了所提出方法的正确性和优越性. |
| 英文摘要 |
| Using the rotor position angle as a subject variable in extended state observer (ESO) and based on high frequency signal injection technique, a novel sensorless active disturbance rejection control system was proposed for interior permanent magnet synchronous motor. The traditional system uses current as a subject variable in its extended state observer and its rotor position value is estimated by integrating the estimated angular velocity value. So the traditional system has the problem that the error of the estimated rotor position value accumulates and increases continuously and is difficult to be eliminated. The proposed method can avoid above problem. The precision of estimated rotor position value is also high when the sine quality of current is poor because of the motor starting or load mutation. The simulation results validate the feasibility and superiority of the proposed scheme. |
