摘　　要：在电动助力车用永磁同步电机(PMSM)控制系统中,针对PMSM在正常运行过程中,发生单相低分辨率位置传感器故障的问题,以霍尔位置传感器为例,提出了一种低分辨率位置传感器故障状态下的新型容错控制算法,将龙伯格观测器引入容错控制并提出一种基于转子位置估算误差的加权值函数,根据该函数值结合基于一阶加速度算法的容错控制,实现永磁同步电机在全速度段的高精度容错控制.实验结果表明,在单相霍尔位置传感器故障状态下,新型容错控制算法具有良好的容错控制效果,提高了电动助力车用PMSM控制系统的可靠性和稳定性.In order to solve the problem of a single-phase low-resolution position sensor failure during the normal operation of the PMSM in the permanent magnet synchronous motor(PMSM)control system for electric moped,a Hall position sensor is taken as an example,and a new type of fault-tolerant control algorithm is proposed in the fault state of the low-resolution position sensor.The algorithm introduces the Luenberger observer into fault-tolerant control and proposes a weighted value function based on the rotor position estimation error.By the function value,combined with the fault-tolerant control based on the first-order acceleration algorithm,the permanent magnet synchronous motor can achieve precision fault-tolerant control in the full speed range.The experimental results show that the new fault-tolerant control algorithm has a good fault-tolerant control effect when the single-phase Hall position sensor fails,and improves the reliability and stability of the PMSM control system for electric mopeds.
