ABSTRACT
In this paper presents a new novel reaching law for sliding mode controlled DC-DC buck converter. The proposed novel reaching law can dynamically adapt to the parameter variations of the controlled system, which allows chattering reduction on control input while maintain high tracking performance of the controller. Chattering analysis presented for both traditional and proposed reaching law. The simulation results are presented to show the better performances of the proposed reaching law and regarding particularly the chattering reduction and high convergence speed on control input in steady state regime.
