Optimization of Torque and Flux ripple for DTC fed Asynchronous Motor Drive Using Hybrid Computing Techniques

This paper presents a comparative study of Space Vector Modulation (SVM)-Direct Torque Control (DTC) of three-phase Induction Motor using conventional PI controller and Hybrid Computing Techniques like Genetic Algorithm tuned PI and Fuzzy Controllers. A dynamic modular model for the three-phase Induction Motor based on Krause’s model is developed and the required supply for this system is provided by a Space Vector PWM based three-phase Voltage Source Inverter. The main characteristics of DTC scheme applied to three phase Induction Motor is studied by simulation, emphasizing its advantages and disadvantages for different configurable controllers.Validation of the proposed system is verified and analysed using MATLAB/SIMULINK tool.
