Content of course unit | Topic 1.1 Terms of management theory: automation, control concepts, automatic and automated control. The main method of automation is a systematic approach. The concept and definition of a system, elements of a system, types of connections between elements: analog, discrete, probabilistic, logical. Topic 1.2 Stages of automation development. Manual operation. The first industrial regulators of Watt, Polzunov, Siemens brothers, indirect action regulator with hydraulic amplifier. Functional diagram of the local SAR. Topic 1.3 Typical functional elements of ATS, definition and purpose. Basic requirements for ATS elements. Principles of regulation: deviation, perturbation, combined, program. Functional SAR schemes that implement management principles. Topic 1.4 Classification of SAR: by the physical nature of the signal, by the type of actuator, by the control law, by purpose, by structure. Further development of automation: the use of microprocessors and controllers, multi-level ATS. Management levels: executive, tactical, and strategic.
