In response to the shortcoming that settling time for nonlinear dynamical systems de-pends seriously on the initial values,the problem of fixed-time synchronization for a class of drive-re-sponse 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 de-signed 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 sys-tems can achieve fixed-time synchronization was proved.Additionally,numerical simulations with dif-ferent control coefficients selected are presented to verify the feasibility of the proposed synchroniza-tion control algorithm.
