A DSP-based sliding mode controller for the planar switched reluctance motor

This paper presents a DSP-based sliding mode controller of the planar switched reluctance motor (PSRM) for precision positioning applications. The mechanical structure, control scheme, and the design of sliding mode controller are presented and analyzed, respectively. The DSP-based sliding mode controller is implemented for the PSRM experimentally. The steady-state positioning errors of x- and y-axes are 0.016 and 0.029 mm, respectively. The effectiveness of the DSP-based sliding mode controller for the PSRM is verified through the experimental results.
