چکیده

-Among all the speed control techniques for induction motor drives, Direct Torque Control (DTC) method is simple and efficient because DTC is independent of machine rotor parameters and free from d-q transformation. Modern DTC based drives are equipped with estimators, observers, and machine intelligence systems to improve the dynamics and efficiency of the drive. This paper is aimed to focus on Sector Advancing Technique (SAT) for reducing the response time of the drive for a known torque command. Simulation studies are carried out using MATLAB/SIMULINK and results of DTC with SAT over conventional DTC are presented. Keywords— Induction Machine, Direct Torque Control, Stator flux, Torque ripple.

Current Limitation and Speed Drop Minimization in Optimal-Efficiency of Induction Motors

In conventional direct torque control (DTC), the stator flux is usually kept constant by controlling the x-axis component of the stator voltage in the stator flux reference frame. The torque is then controlled by the y-axis component of stator voltage. In this scenario, the stator current does not exceed its permissible value. However, in the so-called optimal efficiency mode, the induction mot...
