This paper presents a simple and systematic approach to design sliding mode controller for buck converters. DC/DC switching converters have been used in many applications in recent years. The Sliding Mode Control (SMC) based on Variable Structure System (VSS) theory has been examined for buck switch mode converter type. To obtain a sliding regime, the appropriate sliding surface is selected by assigning poles combined with genetic algorithm. The associated practical problems and the proposed solutions are detailed; like fixed frequency by using pulse width modulation (PWM) as solution and overshoot limitation of the inductor current by using current limiter. A simple and easy to follow design procedure is also described. Simulation results are presented to illustrate the design procedure. The simulation results of the proposed SMC strategy are compared with the adaptive terminal sliding mode control (ATSMC) and PID-SMVC strategies. It is shown that the proposed SMC exhibits a considerable improvement in terms of a faster output voltage response during load changes.
