Abstract

AbstractThis brief proposes a control strategy to regulate the DC/DC Boost converter system affected by line and load uncertainties. The objective of regulating the output voltage in the presence of uncertainties in input voltage and load is met by proposing a non-singular terminal sliding mode control (NTSMC) method combined with a finite-time convergent observer (FCO). The stability of the controller in tracking the reference voltage and regulation of the output voltage is analyzed. Extensive simulations comparison results are implemented to verify the effectiveness of the proposed control method.KeywordsNon-singular terminal sliding-mode control (NTSMC)Finite-time convergent observer (FCO)The DC/DC Boost converter systemCircuit parameter uncertainties and disturbances
