Abstract:

This semester thesis deals with the design of a controller for a non-inverting DC-DC buck- boost converter and its realization on hardware. The special topology of this converter allows to fulfill several design specifications simultaneously: to keep the output voltage of the converter at a constant reference level despite source voltage or load current variations and to drive the system to a loss-minimal state. Therefore, the control structure consists of a combination of feed-forward control for determining the set point of the system with minimal power losses and a state-feedback controller based on model predictive control for counteracting disturbances. The performance of this controller has been investigated in simulations and on hardware.
