研究了一类具有死区非线性输入的不确定混沌系统的控制问题.通过引入死区非线性控制项,有效的消除了实际中由于死区非线性输入的存在而引起的不良控制效果,设计控制器过程中对系统死区模型无需任何限制条件,同时引入扩张观测器,从而只需要知道系统的一个状态.就可以观测出系统待确定的未知信息.对Duffing系统的数值仿真结果表明该控制方案是有效的.
The tracking problem for a class of uncertain chaotic systems in this paper. With the dead-zone nonlinearity in the controller, with dead-zone nonlinearity in the input function is considered the disadvantage can be eliminated. The knowledge about the dead-zone nonlinearity in the input is unnecessary. To make this controller physically used to estimate the unknown information. Numerical simulations are carded out to respect to Duffing oscillator. y realizable, an extended state observer is show the effectiveness of the design with
