本文研究了有限个任意有向图上互连的离散、线性时变、异构子系统的平衡截断问题。子系统之间的信息传输受到一个时间步长的通信延迟的影响。该方法保证了互连结构的保存,并且进一步允许其简化。除了截断与子系统相关联的时间状态之外,该方法还允许与子系统之间的互连相关联的空间状态的降阶,甚至可以去除整个互连。由此产生的误差系统的上界上的nano2诱导的范数。通过实例说明了该方法。
This paper deals with the balanced truncation of discrete-time, linear time-varying, heterogeneous subsystems interconnected over finite arbitrary directed graphs. The information transfer between the subsystems is subject to a communication latency of one time-step. The method guarantees the preservation of the interconnection structure and further allows for its simplification. In addition to truncating temporal states associated with the subsystems, the method allows for the order reduction of spatial states associated with the interconnections between the subsystems and even the removal of whole interconnections. Upper bounds on the ℓ 2-induced norm of the resulting error system are derived. The method is illustrated through an example.
