An Anti-windup Integral Regulator for a DC-DC Boost Power Converter

In this paper, an anti-windup controller is proposed for the output regulation of a direct-current to direct- current (DC-DC)boost power converter. The system is affected by input saturation, modeled as a hard saturation function, which captures the fact that the duty cycle is signal limited between zero and one. In addition, an observer-based extension is discussed, which is useful to obviate the assumption of the input voltage knowledge. Numerical results provides a support for the given theory.
