In this article it is established that any jointly controllable, jointly observable, multichannel, discrete or continuous time linear system with a strongly connected neighbor {communication} graph can be exponentially stabilized with any pre-specified convergence rate using a time-invariant distributed linear control. As an illustration of how this finding can be used to deal with certain distributed tracking problems, a solution is given to a distributed set-point control problem for a continuous-time, multichannel linear system in which each and every agent with access to the system is able to independently adjust its scalar-valued, controlled output to any desired set-point value. To better understand the constraints on controller design, the distributed control problem is recast as a classical decentralized control problem. Armed with the tools of decentralized control, including the notion of a “fixed spectrum,” it is possible to show quite surprisingly that if the only information each agent is allowed to share with its neighbors is its measured output, then distributed stabilization in some cases is impossible. Using well-known decentralized control concepts, lower bounds are derived on the dimensions of the shared sub-states of local controllers which, if satisfied, guarantee that there will be no fixed closed-loop system eigenvalues to contend with. The decentralized control perspective also enables one to assert definitively that without imposing a partitioning constraint, the closed-loop spectrum of any jointly controllable, jointly observable multichannel linear system with a strongly connected neighbor graph, can be freely assigned with distributed feedback control, even in the face of finite delays.
