Abstract :
A new sliding mode controller is proposed for variable speed drive systems which incorporated high field permanent magnet motors. The hardware uses a commercially available three-phase pulse-width-modulator to drive the power bridge. The controller has two conventional current tracking loops with d-q axis decoupling, and an optimal sliding mode speed control algorithm. The sliding mode parameters are directly related to the required system performance in the time domain, simplifying the design procedure. The simulation and experimental results show that the overall system performance is entirely satisfactory
