Abstract
Results on second-order sliding-mode control algorithms are applied to a linear Buck converter in regulation tasks. As usual in SOSMC, chattering, an undesired consequence of sliding control mode, is highly reduced. A basic requirement for the method to be applicable is to find appropriate bounds for the state variables (current and voltage), as well as for the input control. The proposed method has proved to be robust in face of line and load perturbations.
