摘要 主要研究一类在原大系统结构上又逐个地增加了新的子系统的扩展结构大系统基于动态输出反馈的有机结构控制问题。研究了在动态输出反馈条件下扩展结构大系统的数学描述方法,利用Lyapunov稳定性和线性矩阵不等式(LMI)理论给出了此类系统鲁棒关联镇定的充分条件,得到了其动态输出反馈控制器的设计方法,结合算例对所提出方法进行了仿真研究,结果证明了该方法的有效性。 Organically-structured control problem is studied in this paper based on dynamic output feed back for large-scale systems with expanding construction, which is constituted by adding new subsystems on the original construction during the operation. Aiming at this kind of system, the mathematical description of large-scale systems with expanding construction is deduced based on the dynamic output feedback. The sufficient condition of the robust connective stabilization based on dynamic output feedback for the expanding construction system is obtained by using Lyapunov theory and LMI approach. The design method of the dynamic output feedback controller of the expanding construction is given. The system simulation research is carried out for proposed method, and the simulation results show the effectiveness of this method.
