an effective method to control the speed of induction motor. This paper is about the development of the algorithm to do the PWM operation with the help of Matlab Simulink that interfaced with the actual induction motor by Matlab/Real time workshop.

The induction motor speed was controlled by the I/O interface circuit and Simulink to allow the real time control. The control algorithm enables the rotational direction switching and these functions are carried out in Matlab simulation in actual model
