Resumen

© 2004-2012 IEEE. In dc-dc buck power converters, a control action which is negative or greater than one has no physical meaning and is noncausal. For the sake of realism, the nonlinearity accompanying input saturation is taken into account in a model of dc-dc buck power converters, for which a Lyapunov function-based class of proportional-integral with anti-windup (PIAW) algorithms is given. Simple tuning guidelines ensure the global asymptotical stability of the closed-loop system. Neither the class of controllers nor the tuning procedure require the exact knowledge of the parameters of the power converter. To illustrate the results, a novel design matching the proposed class of controllers is given and the results of real-time experimental tests are presented, including the implementation of the linear proportional-integral (PI) control and a known anti-windup (AW) approach. The results confirm that the proposed PIAW control has the best performance even though saturation limits are activated and disturbances are present.
