Distributed adaptive control design for cluster of converters in DC distribution systems

摘要

In this paper, we address the control design problem under the system's model uncertainty utilizing the adaptive control. First, the adaptive control based on the model reference adaptive control technique is presented. Subsequently, the adaptive control technique is applied to a multi-converter system to guarantee the bus-voltage stability and accurate current sharing. Simulation in MATLAB/Simulink is conducted to verify the effectiveness of the proposed control algorithm under typical scenarios including non-linear load change and network topology changes caused by converter failures.
