DIRECT TORQUE CONTROL FOR MATRIX CONVERTER-FED THREE PHASE INDUCTION MOTOR WITH HYBRID PSO

Direct Torque Control (DTC) for Induction Motors using Matrix Converters is a high performance motor control scheme with fast torque and flux responses. This paper presents a new control scheme based on hybrid particle swarm optimization (HPSO). The main advantages of the matrix converter are combines with those of the DTC technique, generating the required voltage vectors under 0.9 input power factor operations. The results demonstrate the good quality and robustness in the system dynamic response and reduction in the steady-state and transient motor ripple torque.
