Control of Induction Motor Drive using Space Vector PWM Simulation Projects


In this paper speed of induction motor is controlled which is fed from three phase bridge inverter. In this paper the speed of an induction motor can be varied by varying input Voltage or density or both. Variable voltage and variable density for Adjustable Speed Drives (ASD) is invariably gain from a three-phase Voltage Source Inverter (VSI).


Voltage and density of inverter can be easily controlled by using PWM method, which is a very important aspect in the use of ASDs. A number of PWM method are there to obtain variable voltage and variable density supply such as PWM, SPWM, SVPWM to name a few


among the various modulation method SVPWM is one of the most efficient method as it has better work and output voltage is similar to sinusoidal. In SVPWM the modulation index in linear region will also be high when compared to other.

The simulation of “Control of Induction Motor Drive Using Space Vector PWM” is carried out in MATLAB/Simulink. The simulation has been done for open loop as well as closed control. The appropriate output results are obtained. The variation of speed of Induction Motor has been observed by varying the load torque in open loop control and results are noted down in the table. Also observed that for the change in input speed commands the motor speed is settled down to its final value within 0.1sec in closed loop model.
