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.
