Modeling, analysis, and robust adaptive fuzzy control for a class of switching power converters

This paper presents a control centric modeling and analysis approach along with a nonlinear control design for a class of switching power converters. A comprehensive model combining the respective state variable models of the interval subsystems is established. Comparison with PSpice simulation justifies the credibility of the model. Based on this model, internal/BIBO stability can be studied for each interval subsystem. Moreover, controllability and observability can also be analyzed to help determining subsequent control configuration. The established model is further investigated for advanced control design, i.e., robust adaptive fuzzy control.
