| 摘 要： | 研究一个新混沌系统的不稳定平衡点的镇定问题.当参数已知时,根据Lyapunov稳定性理论,分别设计了合适的非线性反馈控制器和线性控制器,使受控的新混沌系统期望镇定的任一不稳定平衡点全局指数稳定;当参数未知时,利用自适应策略,构造了相应的控制器使受控系统期望镇定的任一不稳定平衡点渐近稳定.数值仿真结果表明,这些控制方法是有效的. |

| Abstract: | The stabilization of unstable equilibrium points of a new chaotic system is studied. According to Lyapunov stability theory, appropriate non-linear feedback controller and linear state feedback controller are designed to make any unstable equilibrium point exponentially stable when the parameters of system are certain. When the parameters are unknown, by means of an adaptive control strategy, corresponding controller is designed to make any unstable equilibrium point asymptotically stable. Numerical simulations confirm the effectiveness of these control methods. |
| Keywords: | chaotic system stabilization of unstable equilibrium point non-linear feedback control linear feedback control adaptive control |
