摘　　要：研究了一类具有相同线性结构的相似广义组合系统 ,其互联项是非线性的 ,而且含有不确定性·运用lyapnov方法 ,结合组合系统本身的结构特点和一般广义系统理论中状态反馈、受限等价概念 ,设计了状态反馈鲁棒控制器 ,使系统在平衡点处全状态渐近稳定且在状态响应中不包含脉冲项·由于受控系统具有相似结构 ,控制器本身也具有相似结构 ,因此易于工程实现·同时 ,根据不同控制器之间的相似性 ,毁坏的控制器也易于重新实现·研究结果表明 ,相似结构可以简化广义组合系统的分析和设计·Similar generalized composite systems possessing same linear structure were studied. The interconnections of the system are nonlinear and contain uncertainties. By using lyapnov method, the structural characteristics and the concept of proportional state feedback and restricted systems equivalence, the robust controllers were designed,and then the systems are asymptotically stable and have no impulse term in the state responses. Since the controlled systems possess similar structure, the controllers also possess similar structure, they are easy to realize. Meanwhile, the destroyed controllers could be easily reproduced according to the similarity among different controllers. The similar structure can simplify the analysis and design of generalized composite systems.
