摘要：The current paper presents a new, Direct Torque and Flux Control strategy based onsliding mode control (SMC) and space-Vector Modulation (SVM) is proposed for inductionmotor Sensorless drives in order to solve existing problems in conventional control by DirectTorque Control (C-DTC); such as, high flux, torque and current ripple, and variable switchingfrequency. The presence of hysteresis comparators is the major reason for high torque and fluxripples in C-DTC. In SM-DTC, the hysteresis comparators and switching Table are replaced bysliding mode controller. The stability and robustness of the controller are proven analyticallyusing the Lyapunov theory. To avoid the use of a mechanical sensor, the rotor speed estimationis made by a sliding mode observer (SMO) based model reference adaptive system (MRAS).The reference model is a Sensorless sliding mode observer and the adaptive model is a typicalcurrent model. Finally, the proposed schemes are simulated under Matlab / Simulinkenvironment, and the simulation results show the effectiveness of the proposed Sensorlesscontrol.
