电动助力转向(EPS)系统应具有容错性。因此,这篇文章描述了一种估计方法,以重建的位置信号和电流信号的永磁同步电机(PMSM),如果有传感器故障。使用扩展卡尔曼滤波器,它在整个速度范围内运行,也适用于静止前不久的低速,而不需要在设定点电流上添加测试信号。该方法与详细的过程和自适应噪声模型一起工作,以允许在整个速度范围内操作。
Electric Power Steering (EPS) systems should be fault-tolerant. Therefore this contribution describes an estimation method to reconstruct the position signal and the current signals of a permanently excited synchronous motor (PMSM) if there sensors are faulty. An extended Kalman filter is used which operates in the whole speed range, also for low speed shortly before standstill, without the need of added test signals on the set point current. The approach works with a detailed process and adaptive noise model to allow an operation in the whole speed range.
