(eng): One of the features of modern control theory is the growing presence of algebra. Algebraic formalism offers several useful tools for control system design, including the so-called “factorization” approach. This approach is based on the input–output properties of linear systems. The central idea is that of “factoring” the transfer matrix of a (not necessarily stable) system as the “ratio” of two stable transfer matrices. This is a natural step for the linear systems whose transfer matrices are rational, that is, for the lumped-parameter systems. Under certain conditions, however, this approach is productive also for the distributed-parameter systems. The starting point of the factorization
