An output feedback control method is proposed for a class of unknown nonlinear systems. First, the state feedback controller is designed assuming the system state is known, and then the tracking performance is achieved. Then, when the state of the system is not completely measurable, By designing a high-gain observer, the state of the system is estimated to design the output feedback controller, which proves that the designed output feedback controller can obtain the performance of the state feedback controller
