Anita Journal on Electrical Engineering 2230 – 7176 3 2 65 70 Induction Generator, PIC Microcontroller, Simulation, Sliding Mode Control Wind Energy Conversion Systems (WECS) With the growing needs of energy, the use of renewable resources to serve the purpose has been increased. Our paper is just a light into the solution to the crisis that is looming over us. We have designed a controller in the direction of improving the efficiency of Wind energy systems.The approach is based on a sliding mode control methodology, i.e., the system under control is driven towards a sliding mode by tuning the parameters of the controller. In this loop, the parameters of the controller are adjusted such that a zero learning error level is reached in one dimensional phase space defined on the output of the controller.
