Decentralized control with communication between controllers
Jan H. van Schuppen · 2003
this paper around 1995. The plan for this problem is older though, but there are no written records. With Kai C. Wong a necesary and sucient condition was derived, see [20], for the case of two controllers with asymmetric communication. The aspect of the problem that asks for the minimal information to be communicated was not solved in that paper. Subsequent research has been carried out by many researchers in control of discrete-event systems including George Barrett, Rene Boel, Rami Debouk, Stephane Lafortune, Laurie Ricker, Karen Rudie, Demos Teneketzis, see [1, 2, 3, 4, 5, 1, 12, 13, 11, 3 14, 15, 16, 19]. Besides the control problem, the corresponding problem for failure diagnosis has also been analyzed, see [6, 7, 9, 8]. The problem for failure diagnosis is simpler than that for control due to the fact that there is no relation of the diagnosing via the input to the future observations. The problem for timed discrete-event systems has been formulated also because in communication networks time delays due to communication need to be taken into account
