Adaptive output feedback control for uncertain system with static nonlinearity

The problem of control law design for a system consisting of linear stationary and static nonlinear parts is considered. It is supposed that parameters of the linear block are unknown, and its input-to-output transfer function is minimum phase. It is assumed that nonlinear part of the system is known inaccurately, irreducible to the linear block input and, generally, does not satisfy sector restrictions. The regulator ensuring output asymptotic stability is designed. The output of the control system, not its derivatives, is used as a measured variable.
