In this paper the hypothesis of structural equivalence of the systems with internal model is proved. The proof is based on determining common base and structural equivalence of basic structure of the type IMC (Internal Model Control)-control systems. These are predictive control systems, robust systems with internal model and robust systems with conditional feedback.
Keywords: Model Control, Smith prediction systems, robust control systems.
