In this brief, a novel nonlinear tracking control law is presented for dc/dc boost converter voltage control applications through the energy-shaping approach. The first feature is to devise a self-tuner to update the invariant surface according to the output voltage-tracking error. The second is to prove that the exponential convergence and performance recovery properties without steady-state errors under the use of the nominal parameter information of converters. A 3-kW prototype dc/dc boost converter is adopted for experimental verifications of the proposed controller.
