摘　　要：基于系统稳定性理论,设计合适的新型非线性反馈控制器,实现复杂Dynamos混沌系统的状态向量与任意给定的不同参考信号追踪广义投影同步.以追踪控制超混沌系统、混沌系统、正弦余弦信号以及不动点为例,通过改变比例因子,可以获得多个不同混沌系统之间的异结构广义投影同步以及与正弦波形的广义同步,或者将复杂Dynamos混沌系统控制到期望的平衡点.数值仿真进一步表明了该方法的有效性.Based on the system stability theory, a new tracking control method is proposed to acquire asymptotically generalized projective synchronization of full states of a complex dynamos system and arbitrary trajectories. It also allows us to drive a complex dynamos system to arbitrary periodic orbits or fixed point. The technique can direct the scaling factor to a desired value. Sinusoidal waves, chaotic systems, hyper-chaotic systems and fixed points are taken as examples respectively. Numerical simulation results are presented to demonstrate the effectiveness of the proposed method.
