A hybrid passivity based controller design for a three phase voltage sourced reversible boost type rectifier

In this article, we present a criteria to design the switching control sequence for a nonlinear system in a normal form when the control input lives in a finite set. The criteria is based on the minimization of a Lyapunov function and the concept of output regulated subspaces ORS recently presented in [2]. Moreover, we propose to modify the controller by adding a passivity based algorithm in order to improve the transient behavior and reduce the control effort. The technique is applied to the well known three phase Boost type rectifier for which simulations results are provided in order to show the improvement in the transient response. Results are compared with the controller based in sliding mode approach reported in [7].
