TL;DR: In this article, the authors examined several algebraic properties of controlled sequential machines using feedback-induced congruences and applied them to the problem of disturbance decoupling, and showed that feedback congruence can be used to join subsemilattices of the lattice of state set partitions.
Abstract: This paper examines several algebraic properties of controlled sequential machines. We concentrate on the decomposition of controlled sequential machines using feedback-induced congruences. Two special classes of feedback congruences are introduced and shown to form join subsemilattices of the lattice of state set partitions. The results are applied to the problem of disturbance decoupling.
