Abstract

Boost converter is used widely in DC micro-grid.With the heavy use of power electronic devices

Boost converter shows strong non-linearity.In addition

circuit parameter perturbation and external disturbance have serious interference on the control system.In view of above problem

the equivalent model of Boost circuit linearization based on accurate feedback linearization is set up.An adaptive back-stepping sliding mode control method is proposed with combination of back-stepping adaptive control and sliding film control so to solve the control problem of nonlinear systems and the stability problem of unknown disturbance upper limit.It is shown by the simulation result that

in case of sudden change of load and parameter perturbation conditions and compared to the traditional voltage-current double PI control

the proposed method has faster response speed

lower overshoot and stronger anti-jamming performance.
