This thesis investigates a fault-tolerant matrix-converter interior permanent-magnet synchronous motor speed-control system, which uses a predictive controller to improve the dynamic responses. In addition, fault detection and fault-tolerant methods, including current sensors and encoder faults, are proposed to enhance the transient responses, load responses and reliability by replacing the faulty feedback states with the estimated states of the estimator when the sensors are faulty.
A digital signal processor, TMS320LF2407A, is used as a control center to execute the state estimation, control and fault-tolerant methods, which are developed to increase the system performance. Experimental results can validate the correctness and feasibility of the proposed system.
