摘　　要：基于自适应控制方法和Lyapunov稳定性理论,分别在参数完全未知和部分未知的情况下,设计适合超混沌Lü系统广义投影同步的非线性自适应控制器,并进行数值仿真.结果表明,该方法使2个恒同超混沌Lü系统在全局范围内实现广义投影同步,在部分参数未知的情况下,实现了参数的跟踪.Based on adaptive control method and Lyapunov stability theory respectively in the cases of fully and partly unknown parameters, nonlinear adaptive control laws are designed so that the hyperchaotic Lu systems are generalized projective synchronization. Finally, numerical simulations are given to demonstrate the two identical hyperchaotic Lu systems are globally asymptotically generalized projective synchronization. Furthermore, the tracking of parameters in the later case is realized.
