Abstract:

The isolated multisource DC-DC converter allows the bidirectional power transfer between dif- ferent power modules. This converter has to be controlled in a way that the desired power is delivered to these di erent modules and that the desired DC-voltages can be maintained. This project deals with the simulation, design and implementation of an applicable control strategy for this DC-DC converter, which should nally be installed on an autonomous vehicle. In order to test di erent control strategies, a model of the system was elaborated. A strategy to make the system stable and a modulation method to avoid DC currents of the transformer of the converter were developed. A centralized and a decentralized controller were synthesized using open loop shaping and com- pared using the model of the system, whereas better results were achieved with the centralized controller. This controller was updated with a disturbance feedforward structure which is able to calculate the disturbances. Again simulations were made which indicated a better control performance when disturbance feedforward was used. The nal controller was implemented on a DSP-board and evaluated using a hardware setup of the converter.
