Abstract:
In this paper, the output voltage trajectory tracking for the conventional DC-DC boost power converter in the presence of circuit parameter perturbations is investigated. Based on the property of incremental passivity, a simple feedback controller is designed. Meanwhile, to obtain a better disturbance rejection property, we employ two nonlinear disturbance observers (NDOBs) to attenuate the uncertainties in the output voltage and inductor current channels, respectively. Moreover, global trajectory tracking performance of the system under disturbances is ensured. Finally, simulation and experiment studies are offered to confirm the feasibility and efficiency of the presented approach. The related results reveal the proposed controller delivers a nice antidisturbance performance as well as a superior nominal tracking ability.
