Abstract
DC-DC converters are used in every day electronic devices. Like transformers are to ac power, they can change the state of a dc power from high to low and vice versa. In this thesis, the buck converter is designed for specifications of our volition. A Matlab Simulink model of this converter is modeled in open loop, from which is seen the vulnerability of this converter to noise and perturbations in the input power source.
The demand for robust and ultimate controllers has attracted a multitude of researchers in the field of control systems engineering over the years. Ultimate controllers compensate system transfer functions in closed loop and maintain constant and stable output responses, immune to attenuations. The search for this ultimate controller has led to the introduction of controller concepts such as PID, Fuzzy, Sliding mode, Neural and many other control techniques. Here in this thesis we discuss the design and simulation of a PID controller for control of buck converter and the basic concepts of fuzzy control techniques.
