A functional observer design for one-sided Lipschitz nonlinear systems is investigated. The existence conditions for gain matrices of a functional observer are derived based on linear matrix inequalities. Then, a design method for gain matrices of the functional observer is presented. Simulation results show that the proposed approach estimate the states of the system with a high convergence rate of the estimation errors.
