Abstract

This paper considers the regulation problem for a DC–DC buck converter nonlinear system with uncertain components and actuator and sensor failures. We establish a novel reduced-order observer to estimate the unmeasured state. Then, a new fault-tolerant sampled-data controller with an allowable sampling period is constructed to guarantee that the output voltage of the DC–DC buck converter nonlinear system can tend to the desired voltage. Finally, simulation results are presented to demonstrate the effectiveness of the proposed method.
