Abstract :
The notion of generally quasipassive system is introduced. It is shown that for affine nonlinear control systems the general quasipassivity property plus output-to-state stability under zero input plus nonnegativity of certain pseudoscalar product of storage function´s and OSS-Lyapunov function´s differentials implies the existence of output feedback making the closed loop system UB. The result gives method for UB control design for a broad class of uncertain nonlinear systems.
