چکیده:

in this paper a new observer-based backstepping output control design is proposed for controlling a general class of uncertain time -delay chaotic systems . A state observer is utilized to estimate the system states with unknown control direction the control direction is detected based on the nussbaum type function and adaptive backstepping output feedback control is constructed without requirig a priori knowledge of the signs of the control directions which can achieve output tracking.
