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.
