Abstract
In this paper, a simple direct torque control (DTC) method for sensorless matrix converter drives is proposed, which is characterized by a simple structure, minimal torque ripple and unity input power factor. It is possible to combine the advantages of matrix converters with the advantages of the DTC strategy using space vector modulation and a deadbeat algorithm in the stator flux reference frame. The flux and torque error are geometrically put together in a new flux leakage vector to make a stator command voltage vector in a deadbeat manner. To overcome the degrading of dynamic torque response compared to the basic DTC method, an over modulation strategy is presented in the proposed control scheme. Experimental results are shown to illustrate the feasibility of the proposed strategy.
