✦ Synopsis

The following problem is considei I: suppose a controlled system 5 exists with the property that robust tracking and regulation occurs in each of the system's local control agents, and that a new subsystem SncW, which has outputs to be regulated, is to be connected to 5. It is desired to determine: when is it possible to find a local controller for S,,, so that its outputs and all previous outputs are regulated. without the requirement of having IO retune the previous controllers obtained in 5? This is called the espunding s,~srem problem.

It is shown that iI SncW is controllable and observable. and if a solution exists to the robust servomechanism problem for S,,, taken in isolation then for all interconnections and for almost all interconnection gains. there exists a solution to this expanding system problem.
