Abstract

"This paper addresses the practically important question of when a nonlinear system can be asymptotically stabilized with a linear PI control, and show that it is possible if the system can be passified with constant control actions. This result is used to propose a constructive methodology to design PI schemes for switched power converters, which are viewed from a novel perspective: with the switches acting as effective ""port variables"" that establishes a passive mapping with a suitably defined outputs. Detailed calculations are given for the three-phase rectifier and experimental results that compare the performance of the proposed PI with other linear and nonlinear designs. ©2004 IEEE."
