Abstract

In order to improve the stability of the output voltage of the two-stage matrix converter (TSMC) under disturbance load and unbalance load, a control strategy based on expert adaptive PID control is presented. Under synchronous rotating coordinate through d-q transformation, the system adopts the expert PID controllers to trace the given voltage of d-q components. The parameters of PID controller are regulated adaptively and by contrast with the traditional PID control, the closed-loop control system with the expert PID control has the better dynamic performance and stronger robustness. Numerical simulation verified the validity and effectiveness of the proposed control method.
