英文摘要：

Hybrid synchronization of the unified chaotic system with disturbance is investigated. Using the principle of poles assignment method, the switching function is designed to guarantee Anti-synchronization of slide mode with nonlinearity terms. Using modified exponent hitting condition of sliding mode, a robust synchronization controller is proposed. In contrast to the previous works, sliding mode of this controller is free from the influence of disturbance, and the system has both better robustness and quick tracking. Therefore the computation is simple and the conservation is smaller.
