Abstract :
Backstepping is an important adaptive control method. In this note, we have applied it to design the controller of DC-DC buck converter. The buck converter with this controller can accurately track the output signal in the case of parameters uncertainty. Lyapunov criterion proved the stability of the control system and the simulation results showed that the buck converter could quickly reach output target voltage.
