One of most important application of industrial electronics is to keep the speed of induction motors constant at variable load. This paper gives a sufficient method to maintain the speed of induction motor constant, by changing the amplitude of sine reference signal used in generation of PWM using AGC which varied the gain according measuring the change in speed based WSN. The change in gain of reference signal will change the value of rms voltage applied according to the value of change of speed, and this keeps the speed constant.
