Abstract: The control of PWM-type switching dc-dc converters is reviewed. With the difficulties of controller design inherent from the non-linear 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 on-line parameter estimation scheme - the on-line 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 Ćuk converter are provided to illustrate the feasibility and performance of such an adaptive control scheme.
