Abstract :
Robust stabilization with disturbance attenuation performance is considered for nonlinear systems with gain bounded perturbations. Such an output feedback controller is proposed based on two positive definite solution of Hamilton-Jacobi inequalities, that the closed-loop system is exponentially stable (uniformly on the uncertainties) and L2-gain of the closed system is robustly small than one
