Stable inversion-based robust tracking control in DC-DC nonlinear switched converters

— This article studies the robust tracking control problem in nonminimum phase DC-DC nonlinear switched power converters. The proposed procedure introduces a stable inversion-based iterative technique that, taking advantage of Banach’s fixed point theorem, provides closed-form analytic expressions uniformly convergent to the exact solution of the corresponding inverse problem. Then, piecewise constant load disturbances belonging to an a priori known compact set are successfully rejected by means of dynamic compensation. Simulation results validate the proposal.
