一类非线性时滞系统的鲁棒自适应控制

Robust Adaptive Control for a Class of Time-Delay Nonlinear Systems

针对一类含有非线性参数的非线性时滞系统,利用参数分离技术和后推方法,提出了一种自适应状态反馈控制方案,保证闭环系统的所有信号全局一致有界。通过构造Lyapunov-Krasoviskii泛函证明了系统的状态能收敛到零的一个小邻域内。

A design approach to the robust adaptive feedback controller is proposed for a class of parametric delay systems with nonlinear parameters by means of the pareameter separation and backstepping techinique. The globally uniformly boundedness of all the signals in the closed - loop are guaranteed, and the system states are proven to converge to a small neighborhood of zero by constructing Lyapunov - Krasoviskii functionals.
