Wavelet controller design for a micro-PMSM control system

The paper proposes a wavelet controller design for micro-permanent magnet synchronous motor control systems. First, the mathematical model of the micro-PMSM is discussed. Next, a systematic wavelet control algorithm is proposed to obtain the fast responses, good load disturbance responses, and satisfactory tracking responses for time-varying commands. The wavelet control algorithm can be applied for both the speed-loop control system and the position-loop control system. A digital signal processor, TMS 320F28335, is used to execute all of the state estimating algorithms and control algorithms. As a result, the hardware is very simple. Experimental results validate the correctness and feasibility of the proposed method.
