摘　　要：提出和应用延迟微分反馈控制DDFC.对统一混沌系统应用DDFC,对DDFC统一系统的可控性、稳定性进行理论分析与数值仿真.在Matlab下,在事先不知统一系统的不稳定周期轨道UPO及其任何信息下,调节延迟时间τ和控制增益k,寻找和稳定不同的UPO,观察其可控性和稳定性效果.The delayed differential feedback control method is presented. It applied to the Unified system. The controllability and stability of Unified system with the delayed differential feedback control is analyzed theoretically. The numerical simulations show that unstable periodic orbit can be found and stabilized by adjusting the gain k and delayed time τ in numerical simulations under no any information and unknowing unstable periodic orbit of Unified system. We can observe the effects of the controllability and stability in the numerical simulations.
