چکیده:

This paper proposes two DTC branched methods for induction motor in order to increase the methods’ efficiency to utilize Photo Voltaic (PV) cells as power sources. First an improved Predictive Torque Control (PTC) and second a non-hysteresis DTC. In the proposed predictive control the next torque and flux are predicted by discrete model of motor and inverter. Afterward the feasible switching states are examined in a cost function. The switching state that minimizes the cost function has to be exerted during the portion of control interval, instead of the whole interval, in order to minimize the torque ripples. In the non-hysteresis DTC method, dithering technique by superposition high frequency triangular wave is utilized on flux and torque error instead of hysteresis technique. The proposed predictive method and non-hysteresis method is simulated and investigated in three different conditions (mean speed, nominal speed and low speed regions). The results are compared with the response of the simulated modified DTC.
