In this paper, a robust fault detection problem is investigated for a permanent magnet synchronous motor (PMSM). By using the adaptive control and the sliding-mode control strategies, an observer is presented for estimating the amplitude demagnetization fault problem under inductance disturbance. The proposed method can effectively attenuate the inductance disturbance of the PMSM by the sliding-mode strategy. And the adaptive control estimation algorithm is adopted for guaranteeing that the real-time detection of demagnetization flux can be realized. The convergency is obtained by the Lyapunov stability theory. Finally, simulation is given for demonstrating the feasibility and effectiveness of the proposed method.

“…In [6], a robust fault-tolerant predictive current control method is proposed for PMSM considering demagnetization fault, and the fault tolerance and robustness are verified by simulation and experimental results. In [7], a fault-tolerant predictive control algorithm based on active flux linkage is proposed, the SMO is designed to estimate active flux linkage; deadbeat control strategy is adopted to eliminate the error of active flux linkage. The proposed methods in [5]- [7] are all model-based control methods, while the model of PMSM is uncertain when parameter perturbation is considered.…”

In this paper, a robust model-free nonsingular terminal sliding-mode control (MFNTSMC) algorithm based on the ultra-local model is proposed to reduce the influence of permanent magnet (PM) demagnetization for PM synchronous motors (PMSMs). First, the PMSM mathematical model in normal and demagnetization is described, and the ultra-local model of speed loop and current loop is constructed based on the input and the output of the PMSM vector control system. Then, the MFNTSMC method is proposed and adopted to design the speed controller and d-q-axis current controller, and the sliding-mode observer is designed to estimate the unknown terms of the ultra-local model. Finally, compared with the PI control method and model-free control method, the results of simulations and experimentations show that the MFNTSMC method can improve the dynamic response while maintaining robustness of PMSM driven system, reduce the dependence of the design of controller on the precise PMSM model, and has fault-tolerant control function for PM demagnetization fault. INDEX TERMS Ultra-local model, permanent magnet synchronous motor (PMSM), demagnetization, model-free nonsingular terminal sliding mode control (MFNTSMC), sliding mode observer (SMO).
