Therobust adaptive exponential synchronization problem of stochastic chaotic systemswith structural perturbations is investigated\nin mean square. The stochastic disturbances are assumed to be Brownian motions that act on the slave system and the normbounded\nuncertainties exist in all parameters after decoupling. The stochastic disturbances could reflect more realistic dynamical\nbehaviors of the coupled chaotic system presented within a noisy environment. By using a combination of the Lyapunov functional\nmethod, the robust analysis tool, the stochastic analysis techniques, and adaptive control laws,we derive several sufficient conditions\nthat ensure the coupled chaotic systems to be robustly exponentially synchronized in the mean square for all admissible parameter\nuncertainties. This approach cannot only make the outputs of both master and slave systems reach
