Abstract
This paper deals the output voltage control of DC-DC converters in particular the three level boost converter (TLBC). Based on the TLBC mathematical average model, a nonlinear controller using backstepping approach is designed in order to overcome the converter complexity, varying time and nonlinearity. A backstepping control law is determined based on a recursive and systematic design method by two strategy: (i) direct output voltage control and (ii) indirect output voltage control. Besides, the TLBC stability is proved using Lyapunov function criterions. Finally, a variable step and sinusoidal signal in the reference voltage used to validate the establish controller in the Matlab/Simulink software. The simulation results highlight the backstepping approach effectiveness.
