Control Reconfiguration of Dynamical Systems for Improved Performance via Reverse-engineering and Forward-engineering
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 (i.e., 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 maintains. Three practical
applications in the two different classes of target systems, including
consensus in multi-agent systems, Internet congestion control and distributed
proportional-integral (PI) control, show the effectiveness of the proposed
approach.Comment: 27 pages, 8 figure
