This thesis applies the sliding-mode theory to the design of DC- to-DCswitched power converters, which are Buck (with parasitic resistance), Boost and Buck-Boost converters and modeled as bilinear systems. Anew design scheme ofconventional pole- assignment method. Further based on the sliding-modetheory, a reaching-and-sliding region and a stable-sliding region are derived and most importantly the equilibrium point is bounded in theirintersection and shown to be asymptotically stable. In addition,variable structure method in phase-plane is suggested to steer the system into this intersection from the initial condition. One simplesttype of sliding function is also discussed, which only requires the measurement of inductor current. Finally, simulation results demonstratethe success of the proposed sliding-mode technique.
