Self-stabilizing systems are systems that automatically recover from any transient fault. Proving the correctness of a parameterized self-stabilizing system, i.e., a system composed of an arbitrary number of processes, is a challenging task. For the verification of parameterized systems the method of control abstraction has been developed. However, control abstraction can only be applied to systems in which each process has a fixed number of observable variables. In this paper, the authors propose a technique to abstract a parameterized self-stabilizing system, whose processes have a parameterized number of observable variables, to a system with fixed number of observable variables.
