摘要：
An adaptive sliding-mode-like controller for DC-DC buck converters is proposed. Constant switching frequency can be achieved with the proposed approach. An adaptive item is included to adjust the controller parameter online and eliminate the steady-state error. The adaptive scheme is based on a feedback policy that suitably modifies the corresponding power losses term in the controller equation. In addition, this adaptive term will speed up the system response and will stabilise the error dynamics of the closed-loop control system. The controller performance can be examined via traditional small-signal analysis. The implementation of the proposed closed-loop control scheme is illustrated with simulation and experiment.
