摘要：
We consider a control problem of a class of uncertain feedforward nonlinear systems with uncertain time-delays under sensor noise. Time-delays and sensor noise can degrade the control accuracy and as a result, the boundedness of states and output is not guaranteed. To guarantee the boundedness of states and output, we develop an output feedback controller which involves a dynamic gain Moreover, we show that the ultimate bounds of states and output can be arbitrarily small if DC component of sensor noise is zero.
