Digital memory look up based implementation of sliding mode control for dc dc converters
Abstract Switched power electronic converters involve different control actions for different system events. A local control strategy may be developed which reacts only to some local information available to each component without any communication between the different system components located far away in real time. The purpose of this paper is to present a low cost memory based control strategy in a dc dc boost converter. The control employed in this work is based on a sliding mode hysteretic control strategy where the sliding manifold is derived a priori and stored as a look up table in digital memory hardware. The proposed control implementation strategy is low cost and offers a robust dynamic response that is used to mitigate many disturbances in the system.
