一类混沌系统基于观测器的滑模变结构反同步

Anti-synchronization of chaotic system by sliding mode control and observer

利用滑动模态控制研究了含有不确定项的混沌系统的反同步问题,用极点配置原理设计的切换函数保证了带有非线性项的滑动模态混沌反同步,用指数滑模到达条件设计混沌反同步控制器,在该控制器作用下,滑动模态不受干扰的影响,系统有很好的鲁棒性和快速跟踪能力;切换函数的参数方便确定,所得结果保守性小.

The Anti-synchronization of chaotic systems with uncertainty by sliding mode control is studied.Using the principle of poles assignment method,the switching function is designed to guarantee Anti-synchronization of slide mode with nonlinearity terms.Using exponent hitting condition of sliding mode,a robust synchronization controller is proposed.Sliding mode of this controller is free from the influence of disturbance,and the system has both better robustness and quick tracking.therefore the computation is simple and the conservation is smaller.
