Modeling and Optimization of V2Controller for BUCK Converters

The models for BUCK converter and controlling loop were built using state-space average and linear methods and V2control technique, and the parameters for the compensative circuit in the controlling loopwere optimized based on optimal control theory. The simulation results showthat the transient speed of the optimized Buck converter is 50% faster and the bandwidth is about 4 times wider than that designed according to common practices.
