Abstract：In this paper,a new fuzzy control problem for a class of Chua's circuits under impulsive and sto-chastic influences is investigated.The relationship between the eigenvalues and the performance of the sys-tem is first used to define the interval stability of the Chua's circuit system.The definition reflects the con-vergence rate of the system in addition to the stability of the system.On this basis,an intelligent fuzzy controller with adjustable convergence rate is designed to limit the convergence rate of the Chua's circuit while ensuring the stability of the Chua's circuit.The Chua's circuit variable convergence rate algorithm is given,which can speed up or slow down the convergence rate of the Chua's circuit as needed.Finally,the effectiveness and practicality of the proposed control criterion is verified by Chua's circuit system.
