  We propose a distributed control, in which many identical control agents are
deployed for controlling a linear time-invariant plant that has multiple
input-output channels. Each control agent can join or leave the control loop
during the operation of stabilization without particular initialization over
the whole networked agents. Once new control agents join the loop, they
self-organize their control dynamics, which does not interfere the control by
other active agents, which is achieved by local communication with the
neighboring agents. The key idea enabling these features is the use of Bass'
algorithm, which allows the distributed computation of stabilizing gains by
solving a Lyapunov equation in a distributed manner.
