Abstract :
The inherent characteristics of the DC-DC convertors, such as high nonlinearity and time-variation, often result in some difficulties in designing control approaches. Adaptive backstepping sliding mode control method and terminal sliding mode control method are combined in this paper to propose a new kind of adaptive backstepping based terminal sliding mode control for DC-DC convertor to improve control effect. The new method can not only make the system adapt the uncertainty factors, but also enable the system to reach the steady state within a limited time. Simulation results show the superiority of this combination approach.
