Industrial Control
Unit: 3Prerequisite: Linear Control SystemsGoal: Introduction to various industrial control structures and methods of design and implementation of controllers in industries.Course Description: Definitions and generalities: industrial process, benefits of automation, elements of automation, process modeling and control, PID controllers.Industrial automation: introduction, schematic of system control from hardware to DCS and then FCS, introduction to PID and PLC: basic principles, hardware, programming methods, ladder programming, develop a simple program, examples of PLC applications in industries.Process modeling: modeling based on the physical principles governing the process, deriving state equations, introducing and modeling the mechanism of control of level, flow, pressure, temperature and densityProcess identification: static modeling, dynamic modeling for first and second order systems without delay, integral processes, oscillatory systems, introducing controllability ratio and final normalized gain, frequency response methods, Ziegler-Nichols frequency response methods, relay feedback method, modern parameter identification methods, least square methods, high order continuous and discrete systemsDesign adjust and implementation of PID controllers: criteria for controller design, introducing different parts of PID controller, summation (saturation) effect of integrator, types and methods of implementation, introducing an industrial PID controller, DDC methods, Ziegler-Nichols time based adjusting methods, ISE, IAE, Ziegler-Nichols frequency based adjusting methods and other methods, specification of PID, delay system and high order systemsIntroduction of control structure in industry: on/off controllers, feed forward, cascade, selective, override, ratio control, split rangeText books:1.
