The study proposes a wavelet controller design for micro-permanent magnet synchronous drive systems. 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 control algorithms. As a result, the hardware is very simple. Experimental results validate the simulated waveforms and show the correctness and feasibility of the proposed method.
