| 摘 要： | 本文研究了具有不确定结构的随机高阶下三角系统鲁棒控制问题，对这类问题采用幂积分器的方法结合积分反推的思想给出一个光滑控制器使得系统的解最终趋向于原点附近任意小的邻域，并对具有外部干扰时设计了一个光滑控制律实现鲁棒干扰抑制。

| Abstract: | We study the robust control design of stochastic high-order lower-triangular systems with structure uncertainties. By power integrator and backstepping technique,we give a controller that can make the states go into the arbitrary small neighborhoods asymptotically. Further in the existence of external disturbance,we also design a smooth controller to implement the disturbance attenuation. |
