Show moreThis thesis proposes a unified boundary control law for DC-DC converters (Buck, Boost, and Buck-Boost) which improves both the transient and steady state response in comparison to boundary control laws using first or second order switching surface. A new set of switching zones on normalized state plane are defined to decide switching behavior every sample period. Additionally, non-ideal operations and a parameter self-adaptive algorithm are proposed and verified in simulation. The parameter self-adaptive algorithm enhances the system robustness and reduces the parameter sensitivity. The transient bandwidth for the load disturbance rejection and command tracking approaches the physical limits of DC-DC converters. Simulation results are presented to illustrate the major benefits of the proposed uni ed boundary control law. M.S. in Electrical Engineering, May 2015 Show less
