By the study of the output feedback control of nonlinear systems, its sufficient condition for the solvability is proved, and a form of the state observer is presented.

The output feedback controller can be obtained based on the states of the iterative learning observer and tuning parameters.

The linear output feedback controller can make the closed-loop dynamical system stable in the sense of uniformly ultimate boundedness, and the improved nonlinear output feedback controller can uniformly make the closed-loop dynamical system.
