Abstract :
Nonlinear backstepping adaptive controller is proposed for the design of parallel DC-DC buck converters with uncertainties of load and power disturbance. Global asymptotic stability of the system is proved by Lyapunov stability theory. The relationship between the control elements and circuit parameters is determined by simulation analysis. The simulation results demonstrate the effectiveness of the presented method.
