چکیده
This paper places of interest Direct Torque control (DTC) strategy for induction motor based on fuzzy logic control. Many methods of controlling the performance of induction motors exist. The direct torque control deserves special attention because of high performance vector control based on decoupling the stator flux and electromagnetic torque. In conventional method normal DTC is used to control the torque, but main drawback torque ripple is high. The proposed scheme with use of fuzzy logic the stator flux is compensated, the selection of the most suitable duty cycle value for every switching period is done, so the switching frequency of the inverter is maintain as constant. Hence the torque ripple is reduced.

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...
