Abstract :
In this paper, the problem of H∞ filtering for a class of nonlinear systems based on prey-predator model is considered. Taking into account the nonlinearity of the prey-predator systems, the model of these systems is constructed. Then, via Lyapunov stability theory and linear matrix inequality technique, the method of H∞ filter design for nonlinear prey-predator systems with stage structure and external disturbances is also proposed. Finally, a numerical example is introduced to demonstrate the effectiveness of the proposed approach.
