摘要：

A new fault detection and tolerance (FDT) control strategy for current sensors of permanent magnet synchronous machine drive in filed-oriented control mode was introduced in this paper, based on the reasonable estimation of current amplitude. The propounded method can be applied to deal with a single or double signal-loss faults (two concurrent or independent faults), and shows the capability of online revision to gain variation and zero offset. Compared with the conventional observer-/model-based fault detection methods for current sensors, the proposed method only requires the information of three-phase currents and the position of motor rotor, instead of an accurate system model with explicit parameters. The improved simplicity and reliability makes this new method especially useful for FDT of current sensors in a real-time control system with limited computational capability. The feasibility and robustness of the proposed approach has been validated by extensive experiments under a wide variety of working conditions.
