We derive a general exponential stability condition for linear time-varying
distributed networked control systems, using the Lyapunov direct method. We then
propose an algorithm for designing a communications (feedback) network that
satisfies this stability condition with minimum number of communication links,
thus reducing the cost and complexity of the required communications network. We
will also propose a procedure for updating feedback gains and the topology of
the communications network as the dynamics network parameters change in time.
