| 摘要: |
| 针对一类具有不确定参数和外界扰动的非线性大系统，在子系统互连项上界具有多项式形式的条件下，提出了一种分散变结构模型跟随控制器设计方案。该控制器不需要未知参数变化、外界扰动以及子系统互连上界的先验信息，能够通过自适应率对上述信息进行在线估计。在保证闭环大系统渐近稳定的条件下，同时实现了各个子系统滑动模态的存在性和可达性。理论分析和仿真结果验证了本文所提方案的有效性。 |

| Abstract: |
| A decentralized variable structure model following controller is designed for a class of uncertain nonlinear large-scale systems with interconnections whose upper bounds have the form of polynormials. Without a priori knowledge of the upper bounds of unknown parameters, interconnections between subsystems and extemal disturbances, the stability of the closed-loop large-scale system is guaranteed by adaptive laws. Furthermore, the sliding mode of each subsystem exists and is reachable. Theoretical analysis and simulation results show the effectiveness of the controller. |
