Self Managed Systems - A Control Theory Perspective

Taylor, Richard; Tofts, Chris

HPL-2004-49

Keyword(s): self-management; control; distributed

Abstract: Self-managed systems are essentially closed loop control systems. When designing such systems we should ensure that they do not allow fundamentally bad properties, too slow convergence, oscillation, chaotic behaviour, stuck modes; just as for any control system. How can we perform these checks in the presence of arbitrary (Turing complete) control functions? We argue that the space of control functions and compositions should be restricted to those with known 'good' properties and demonstrate such a space within cellular automata.
