基于逆向和正向工程的动力系统控制重构
Control Reconfiguration of Dynamical Systems for Improved Performance via Reverse- and Forward-engineering
摘要：
本文提出了一种控制重构方法来改善两类动力系统的性能。最近的研究重新设计的信息物理系统的动机，我们提出了一个三步控制改造过程。首先，我们对一个动力系统进行逆向工程，以挖掘出它实际解决的优化问题。其次，我们通过应用相应的更快的算法来解决这个优化问题，从而对系统进行正向工程。最后，通过比较原动力学和加速动力学，我们得到了重新设计的部分（额外动力学）的实现。结果，给定系统的收敛速率/速度或瞬态行为可以得到改善，同时保持系统控制结构。互联网拥塞控制和分布式比例积分（PI）控制，作为应用程序中的两个不同类别的目标系统，被用来显示所提出的方法的有效性。
英文摘要：
This paper presents a control reconfiguration approach to improve the performance of two classes of dynamical systems. Motivated by recent research on re-engineering cyber-physical systems, we propose a three-step control retrofit procedure. First, we reverse-engineer a dynamical system to dig out an optimization problem it actually solves. Second, we forward-engineer the system by applying a corresponding faster algorithm to solve this optimization problem. Finally, by comparing the original and accelerated dynamics, we obtain the implementation of the redesigned part (the extra dynamics). As a result, the convergence rate/speed or transient behavior of the given system can be improved while the system control structure is maintained. Internet congestion control and distributed proportional-integral (PI) control, as applications in the two different classes of target systems, are used to show the effectiveness of the proposed approach.
