Abstract: A slide mode control－common model control（SMC－CMC） controller was proposed to deal with the time－variable and complexity of the switching mode power converters．Using the state－space average modeling method，a nonlinear model of BUCK converter working on current conduction mode （CCM） was set up．Dynamic neural network which was constructed based
on a number of integrators and RBF neural network was employed to approximate the inverse model of the dynamic system． Using this inverse model to build a CMC controller．The introduction of slide mode control was to improve the robustness of controller．The modeling and simulation of system was implemented under Matlab／Simulink．The result of simulation confirms
show that the SMC－CMC control schemes are capable of reduced steady state error and improve controll‐er's reliability during supply change and load variations．
