Unknown System Dynamic Estimator-Based Two-Phase Power Reaching Law Control for DC-DC Buck Converter

In this paper, an unknown system dynamic estimator-based reaching law control scheme is proposed for buck converters with parameter uncertainties, input voltage fluctuations and load variations. By utilizing a first-order low-pass filter, a simple unknown system dynamic estimator (USDE) with only on...
