Using improved state-dependent Riccati equation method,the state synchronization of unified chaotic systems is achieved. The state adjustors with given stability improve the dynamic performance of system synchronization. Theoretical deduction and simulation researches show that the error systems are asymptoticly stable. The comparative simulations with the traditional state-dependent Riccati equation method verify the improvement in dynamic performance of system synchronization.
