首先给出Marotto意义下FitzHugh-Nagumo离散模型存在的混沌现象及其动力学行为,然后利用非线性反馈线性化的轨迹跟踪控制原理为FitzHugh-Nagumo离散模型设计控制器,最后将模型稳定到不动点或周期轨道上,数值仿真结果验证了该方法的有效性.
The existence of chaos of the discrete FitzHugh-Nagumo model is given in the sense of Marotto and the dynamical behavior which the model has. The controller of the discrete FitzHugh- Nagumo system is designed by principle of chaos tracking control. Finally, the system is controlled in the positive fixed point or a given periodic orbit, the conclusion is validated by simulation.
