摘要

摘要: 在高性能的水下航行器推进系统中, 为了解决由于永磁同步电机(PMSM)单相霍尔位置传感器故障, 导致的转子位置估算不准确、电机无法正常驱动等问题, 提出一种新型容错算法。首先将故障加速度引入传统平均速度法, 构建改进1阶加速度容错算法, 在改进1阶加速度容错算法估算转子位置的基础上，建立电流滑模观测器, 通过锁相环提取容错后的转子位置; 然后针对单相霍尔位置传感器故障状态, 将改进1阶加速度容错算法与滑模观测器的观测结果根据权值协调输出; 最后, 通过试验验证了单相霍尔位置传感器故障类型下的控制系统性能。试验结果表明, 新型容错算法提高了传统霍尔位置传感器PMSM控制系统的稳定性和可靠性, 有效改善了推进系统在故障情况下的加速性能, 优化了容错控制效果。

Abstract: A new fault-tolerant control algorithm for the permanent magnet synchronous motor (PMSM) in high per-formance underwater vehicle propulsion system is proposed in order to solve the problems of inaccurate rotor position estimation and abnormal motor driving caused by Hall position sensor fault. Based on the traditional mean velocity method, fault acceleration is introduced to construct an improved first-order acceleration fault-tolerant control algorithm. This improved first-order acceleration fault-tolerant algorithm is adopted to estimate the rotor position, and then a current sliding mode observer is established to extract the fault-tolerant rotor position through a phase-locked loop. For the fault state of single Hall sensor, the result of the improved first-order acceleration fault-tolerant algorithm is coordinated with the observation result of the sliding mode observer to output according to their weights. Finally, the performance of the control system for the fault type of single-phase Hall position sensor is verified by experiments. Experimental results show that the new fault-tolerant algorithm improves the stability and reliability of the traditional PMSM control system with Hall position sensor. The acceleration performance of the propulsion system in the case of fault is effectively improved, and the fault-tolerant control effect is optimized.
