【Abstract】 In response to the shortcoming that settling time for nonlinear dynamical systems depends seriously on the initial values, the problem of fixed-time synchronization for a class of drive-response chaotic systems was investigated by combining T-S fuzzy theory and using a semi-intermittent synchronization control method. In the part of theoretical analysis, the corresponding controller was designed based on the fixed-time stability theory of differential equations. By constructing a Lyapunov function and employing inequality techniques, the conclusion that the given drive-response chaotic systems can achieve fixed-time synchronization was proved. Additionally, numerical simulations with different control coefficients selected are presented to verify the feasibility of the proposed synchronization control algorithm.更多还原
