This invention provides a health management method for an unmanned surface vessel's integrated power system. It employs fault prediction-based early warning and system reconfiguration-based fault recovery, enabling fault early warning / pre-location, fault reconfiguration / pre-reconfiguration, and maintenance recommendations. This ensures the healthy operation of the integrated power system during unmanned surface vessel operation. During unmanned surface vessel operation, real-time monitoring of data reflecting the operational information of various devices in the integrated power system is performed. Alarm judgments are issued for each monitored data point. When a monitored data point exceeds a set threshold, a steady-state assessment is conducted. For monitored data determined to be in a non-steady-state state, a trend assessment is further performed. If the trend is normal, it indicates that the integrated power system is operating normally; if the trend is abnormal, fault location is performed, and then fault reconfiguration is carried out based on the fault location results.

The invention discloses a five-phase permanent magnet synchronous motor dead-beat fault-tolerant direct torque control method based on harmonic current closed-loop suppression, and the method comprises the steps: firstly constructing a subspace and a virtual voltage vector in the subspace based on a principle that the harmonic current of the subspace is suppressed to be zero in a normal operation state of a motor; and then, analyzing the distribution characteristics of a double-sub-space virtual voltage vector under any phase open-circuit fault, introducing a simplified dead-beat direct torque control structure, and inhibiting motor open-circuit disturbance by combining a disturbance observer. Furthermore, a virtual voltage vector of the subspace is selected in an open-circuit fault state, and the virtual voltage vector is combined with deadbeat direct torque control to realize closed-loop suppression of harmonic current of the subspace, so that the system can effectively suppress third harmonic current in both normal operation and fault states. According to the method, open-circuit fault diagnosis and system reconstruction are not needed, the torque ripple and the third current harmonic can be suppressed at the same time, and the method has a good engineering application prospect.
