摘 要: | 针对电动汽车永磁同步电机无位置传感器控制系统,在两相静止坐标系(d—B)内将滑模观测器法与MRAS结合,提出了基于模型参考自适应的滑模观测器,并利用自适应律估计永磁同步电机的转子速度。仿真和试验表明无位置传感器控制方法是切实可行的。

Position Sensorless Control for Permanent Magnet Synchronous Motor in Electric Vehicle |

Abstract: | This paper presents a new adaptive slid-mode observer for electric vehicle permanent magnet synchronous motor(PMSM) sensorless control system, which is combined with the sliding mode observer and model reference adaptive method in the two-phase stationary reference frame. The speed of PMSM rotor is estimated by adaptive law. Simulation and experimental results show that the sensorless control method is practical and feasible. |
