摘要：
The grid-side current inner loop and DC-link voltage outer loop are common used in the single-phase PWM rectifier control system. Once an unexpected failure occurs in the sensors of the detection system, which may cause the deviations of feedback values, the control performance and the operation safety of the rectifier will be affected. This paper presents an accurate and reliable scheme of fault diagnosis and fault tolerant control for the grid-side current and DC-link voltage sensor faults in single-phase PWM rectifier control system. The analytical redundancy is utilized in fault diagnosis. In terms of different switching function values under unipolar and bipolar modulations, the sliding mode observers and state estimators are designed. The system residuals are generated by operating measured and observed values. The fault diagnosis unit locates the faulty sensors by comparing residuals with thresholds. The fault tolerant control method is quickly employed after the fault is detected. The measured values from faulty sensors are replaced by observed values in system reconfiguration. Three types of sensor faults were carried out through simulations and experiments. The results have verified the effectiveness and reliability of the proposed strategy. © 2017, The editorial office of Transaction of China Electrotechnical Society. All right reserved.
