Control and Cybernetics

چکیده
Abstract: The paper gives a basis for solving many problems of numerically reliable synthesis of sub-optimal discrete-time control in H∞. The approach is based on J-lossless factorisations of the delta-domain chain-scattering descriptions of continuous-time plants being controlled. Relevant properties of poles and zeros of chainscattering models are given. Necessary and sufficient conditions for the existence of stabilising J-lossless conjugators are presented and discussed. Some aspects of numerical conditioning of synthesis of such conjugators are considered. A numerical example illustrating synthesis of stabilising right J-lossless conjugators is also included.

—The three greatest theories in science and engineering developed in the 1940s are cybernetics, information theory, and systems theory. Cybernetics is the science of communication and control in humans, machines, organizations, and societies across the reductive hierarchy of neural, cognitive, functional, and logical levels. A contemporary form of cybernetics, known as cognitive informatics (CI...
