This paper investigates global robust synchronization of a class of nonautonomous chaotic systems with parameter mismatch under the master-slave variable substitution control. A criterion of linear matrix inequality (LMI) for the global robust synchronization is rigorously proven and the corresponding synchronization error bound is analytically estimated. The LMI criterion is then applied to the gyrostat systems, obtaining some simple and optimized algebraic criteria for global robust synchronization of the master-slave gyrostat systems with time-varying phase mismatch under single-variable substitution configurations, further verified in a numerical example.
