Abstract

The control of PWM-type switching DC-DC converters is reviewed. With the difficulties of controller design inherent in the nonlinear nature of the converters properly addressed, an innovative adaptive digital controller is proposed. This controller will make use of a grid-point concept to characterize the operation space of the controlled DC-DC converter. In conjunction with a novel online parameter estimation scheme--the online simplex algorithm--and a robust control law, the objectives of adaptivity to wide operating range, disturbance rejection, stability, and satisfactory transient responses are achieved. Simulation results on a published Cuk converter are provided to illustrate the feasibility and performance of such an adaptive control scheme.
