PWM-Based Finite-Time Tracking of Switched Buck Power Converters

PWM-Based Finite-Time Tracking of Switched Buck Power Converters

In this paper, the problem of finite-time tracking is investigated for switched buck power converters based on the pulse width modulation (PWM) technique. For the continuous model, an equivalent continuous controller is solved by the backstepping technique, such that all signals are finite-time stab...
