Abstract: An internal model control using a conditional integrator compensator is proposed for the robust output regulation of a DC/DC buck converter. Based on the input-output linearisation from the state-space averaged model of the DC/DC buck converter, the robust output regulation problem of this type of converter can be converted into a robust stabilisation problem of an augmented system consisting of the given buck converter and the internal model by introducing a proper internal model. Another advantage of the proposed method is to sense the capacitor current instead of the inductor current. The effectiveness of the proposed converter is verified by comparing the proposed controller performance with single-loop PI control and double-loop PI control under load disturbances and supply voltage variations.
