The main issue of this work is to analyze and to test how the characteristic curve of the induction machine can be adjusted by the power electronic devices, when these are integrated into rotor circuits. In order to technically analyze the characteristic performances of the induction machine by switching between cages, the simulator software's MATLAB and NETASIM have been used. The simulated current-...
Based on fuzzy control strategy, direct torque control (DTC) system of induction motor is designed by making use of a fuzzy controller to choose voltage-space-vectors. Simulation model of this system is realized via Matlab software. Finally, simulation results show that this system has improved dynamic and static performance that the response of torque gets quicker, and the fluctuation of torque turns...
The modern technique of direct torque control induction motor is modified in this paper. Machine analysis is emphasized directly on the 3-phase variables for motoring mode, so Park's transformation to generalized d-q axis theory is not used. Only stator current signal is functioning to evaluate fluxes and speed, so that no need to use any sensor. The 3-phase PPU inverter gate is excited by the control...
