中文摘要
      针对一类具有动静态关联项和未建模动态的时变关联系统, 通过引入输入滤波器及一系列坐标变换, 给出了一种分散自适应输出反馈控制器的设计方案. 当时变参数的变化率属于L1∩ L, 外界干扰属于L1∩ L, 未建模动态的幅值在某些范围内变化时, 证明了闭环系统的稳定性, 且每一个子系统的输出收敛于零. 仿真例子验证了这一控制方案的有效性.
英文摘要
      For a class of time-varying interconnected systems with dynamic and static interconnections and unmodelled dynamics, by introducing input filters and a series of coordinate changes, a design scheme of decentralized adaptive output feedback controller is given. It is proved that when the variation rates of time-varying parameters belong to L1 TL1, disturbances will belong to L2 TL1, and the magnitude of the unmodeled dynamics is varying in some ranges. The stability of the closed-loop system is proved, and the output of each subsystem converges to zero. A simulation example demonstrates the effectiveness of the control scheme.
