ABSTRACT: This paper proposes
an output feedback nonlinear general integral controller for a class of uncertain
nonlinear system. By solving Lyapunov equation, we demonstrate a new
proposition on Equal ratio gain technique. By using Equal ratio gain technique,
Singular perturbation technique and Lyapunov method, theorem to ensure regionally
as well as semi-globally exponential stability is established in terms of some
bounded information. Moreover, a real time method to evaluate the ratio
coefficients of controller and observer are proposed such that their values can
be chosen moderately. Theoretical analysis and simulation results show that not
only output feedback nonlinear general integral control has the striking
robustness but also the organic combination of Equal ratio gain technique and
Singular perturbation technique constitutes a powerful tool to solve the output
feedback control design problem of dynamics with the nonlinear and uncertain
actions.
