非线性振子混沌运动的控制研究

Study on Controlling Chaotic Motion of a Nonlinear Oscillator

研究了一类同时含有平方项和立方项，且带有不确定性参数的受迫非线性振子混沌控制问题。采用速度梯度自适应控制方法，使其从混沌运动返回到周期运动。仿真结果表明，该控制策略是有效的。

In thispaper, w econsiderthe problem ofchaoscontrolin a class offorced vibration system with both square and cubic nonlinear term s and uncertain param eters. Speed gradientadaptive controlm ethod isused to direct chaotic m otion to a periodicm otion. The sim ulations dem onstrate the efficacy ofthe adaptive controlstrategy.
