摘要:
针对三相永磁同步电机驱动系统中的位置/速度传感器和电流传感器开路故障问题,提出 基于滑模观测器的故障检测与系统容错方法。通过建立系统的滑模观测器模型,获得系统输出电 流与速度信号的预测值,利用预测值与系统实际输出值的残差分析并检测系统的传感器故障,在故 障被检测的情况下,针对电流传感器,提出了一种 V/f 控制算法以实现故障情况下系统的平滑切 换; 针对位置/速度传感器,提出一种反电动势直接计算法以实现故障情况下系统的平滑切换,实验 结果表明: 所提出的算法能够在线检测故障并实现故障前后系统平滑切换与容错控制。?
Abstract:
Aiming at open-circuit fault of speed and current sensor in three-phase permanent magnet synchronous motor drive system, a sliding mode observer based fault diagnosis and reconfiguration method was proposed by establishing the sliding model of the motor system to obtain the predicted currents and speed. Faults were detected by the residuals between the predicted and real signals. Aiming at current sensor fault which was detected, a V/f based control strategy was proposed to realize fault tolerant, and aiming at speed sensor fault which was detected, a direct calculation of back electromotive force based control strategy was proposed to realize fault tolerant. The convergence and tuning efforts of sliding mode observer were analyzed, and performance of healthy system and reconfigured system was compared. Eperimental results show the fault can be detected and smoothly switched to tolerant system.?
