Abstract: Many industrial supplies depends on switched mode power supplies, they need well regulated supply. For this a new online system identification is used. The proposed method can be applied to many alternative applications where efficient and accurate parameter estimation is required. In the existing method, a three mode PID controller is used which offer several disadvantage which need a continuous tuning and constant gain parameter. The proposed method uses the fuzzy logic controller for the voltage compensation where the design is based on the knowledge base and rule base and the above disadvantage can be eliminated. The novel technique is computationally efficient, based on a dichotomous coordinate descent algorithm and uses an infinite impulse response adaptive filter as the plant model. Simulation analysis and validation based on experimental data obtained from a DC-DC buck converter is validated using MATLAB/SIMULINK.
