2- Modern control The early history of the PLC & DCS goes back to the 1960’s when control systems were still handled using relay control. During this time the control rooms consisted of several walls containing many relays, terminal blocks and mass of wires. The problems related to such kind of systems were many, among those one could mention:

Classical Control Topics covered: Modeling. ODEs. Linearization. Laplace transform. Transfer functions. Block diagrams. Mason’s Rule. Time response specifications. Effects of zeros and poles. Stability via Routh-Hurwitz. Feedback: Disturbance rejection, Sensitivity, Steady-state tracking. PID controllers and Ziegler-Nichols tuning procedure.

The fundamental goal of CE is to find technically, environmentally, and economically feasible ways of acting on systems to control their outputs to a desired level of performance in the face of uncertainty of the process and in the presence of uncontrollable external disturbances acting on the process. Act.

To design such a system, an engineer will need to draw up a sensor circuit diagram, which tells them how to link all the components of the circuit together. In this article, we’ll take a closer look at the basics of sensor circuit diagrams, including what goes into making one and how they’re used.
