A feedback compensator design procedure for switching regulators
Abstract
The state-space modeling technique described by Middlebrook and Cuk (1976) is used to derive a set of linear state equations that approximately represent the dynamics of a power converter stage. Techniques of modern control theory are applied to obtain a class of state-feedback control laws. The resulting closed-loop system has desirable steady-state and dynamic performance characteristics. The design procedure is an iterative process involving (1) selection of performance index weighting factors, (2) use of digital computer programs to calculate the resulting control laws, (3) computer simulation of the actual circuit response, and (4) modification of performance weighting factors.
