Time-optimal sliding-mode control for multi-quadrant buck converters

A new development of time-optimal control systems in multi-quadrant buck converters for output regulation in minimum time is presented. Pontryagen´s minimum principle is employed to obtain time-optimal control law for linear constrained input control systems. Applying this method, transient performance of system variables is improved for output regulation of any disturbance. Some numerical simulations and experimental results are shown to prove the effectiveness of the proposed technique in comparison to the classical sliding-mode control method.
