Research output: Contribution to conferencePaperpeer-review

Abstract

A direct pole-placement control strategy is introduced, and applied in the design of a buck type, dc-dc converter. The solution involves a feedforward component in the control strategy, to eliminate steady-state errors. The value of the feedforward gain which completely eliminates steady-state error, is dependant upon the gain of the plant, which may not be known exactly. In this design the feedforward gain is determined adaptively, so as to drive the steady state error to zero.
