Abstract:
 Regarding to the stability limitation of the traditional linear control,an improved nonlinear control
strategy derived on Lyapunov direct method was proposed for the single phase Buck inverter. On the
basis of the quasi steady state average model of the proposed system,a quadratic energy-like Lyapunov
function was presented and as well as its control law,which a stable convergence of the proposed system.
The duty cycle of the control equation was carried out by using integral reset circuit. Implementation of
the proposed controller is simple. Moreover,the stability of the proposed system was verified in theory
and system performace analysis was shown,including the model comparison results between the proposed
system and the traditional PID control one. Finally,the experimental circuit was conducted. The proposed
experiment results show the correctness of theoretical analysis and the feasibility of the proposed
Lyapunov control scheme.
