A controller resetting strategy for the stabilization of DC-to-DC power converters towards non-minimum phase equilibria

A feedback resetting strategy, exercised on the output of a purposely designed unstable dynamical feedback controller, is shown to yield a robust, and efficient, output voltage stabilization of nonlinear average models of DC-to-DC power converters around any non-minimum phase equilibrium point of the system. The technique guarantees, in an average sense, an asymptotically stable behavior of the controlled converter state variables towards their required equilibrium values, while the unstable dynamical compensator output is forcefully kept bounded within an arbitrarily small neighborhood of the required controller operating point.<>
