The Model Predictive Torque Control is used as a control strategy for induction machine due its quick dynamic reaction, intuitive nature, and flexibility to integrate limitations. Model predictive torque control (MPTC), an upgraded form of Direct Torque Control (DTC), is a frequently used control method for induction motor drives. To reduce torque ripples, PI-based MPTC was traditionally used. It does not, however, solve the reliable and accurate tracking of speed. In this paper, a TSMC-based MPTC scheme is developed, which combines the features of TSMC and Model Predictive Control (MPC) to produce a robust and adaptable system that enhances tracking performance while minimizing torque ripple. The MPTC chooses the best switching states to minimize the cost function; the motor parameter behavior changes with time, and the variation in motor parameter affects the motor performance. To successfully suppress variation, a modified MPTC having torque variation updating mechanism is employed. The purpose of terminal sliding mode control is to soften the speed approach to the reference value. The result is demonstrated in Matlab/Simulink. The use of a TSMC-based Model Predictive Controller for rapid and quick dynamic torque response of an IM motor has been demonstrated through simulation results (MPC). For parameter uncertainties and speed variation, the proposed control strategy has a higher performance validity than conventionally tuned PI, SMC control schemes.
