| Abstract | ||
| The purpose of this paper is to analyze, study and simulate a three-phase induction motor drive using vector (field-oriented) control strategy and PWM current regulated inverter using hysteresis band current controller. The mathematical model of the induction motor and the principle of indirect field-oriented control are introduced. The Sliding Mode Controller with Boundary Layer (SMC-BL) is used as a speed controller and compared with the proportional integral (PI) controller. A Simulink / Matlab program is written for simulating the induction motor model, SMC-BL and PI controllers and indirect field oriented control. The SMC-BL based system and PI-controller based system are compared from the point of view of speed–time response and load disturbance. The simulation results which illustrate the performance of SMC-BL based system and PI-controller based system are plotted and discussed. These results obtained have shown improvement in the SMC-BL system performance from the point of view of variable speed tracking and load disturbance | ||
