DTC of Matrix Converter Fed Induction Machine Based on Fuzzy Logic

摘要

In this paper the FLDTC for IM fed by matrix converter (MC) is proposed. The DTC yields fast response and the matrix converter has less weight and compact in size. The drawback of the large ripples of torque in conventional DTC method is overcome using fuzzy logic. Ripple contents are reduced by using the proposed controller. Also the starting performance of the IM is improved. The comparison of the results of IM drive using FLDTC compared with the conventional DTC is shown. The result shows the enhanced performance using the proposed controller. The comparative results in steady state and at starting conditions are shown and analyzed.
