Process-control-flow diagram, used in process management; Quality-control-flow diagram, used in quality control. In software and systems development, control-flow diagrams can be used in control-flow analysis, data-flow analysis, algorithm analysis, and simulation. Control and data are most applicable for real time and data-driven systems.
A functional block diagram, in systems engineering and software engineering, is a block diagram that describes the functions and interrelationships of a system. The functional block diagram can picture: [1] functions of a system pictured by blocks; input and output elements of a block pictured with lines; the relationships between the functions ...
Flow diagram is a diagram representing a flow or set of dynamic relationships in a system. The term flow diagram is also used as a synonym for flowchart, [1] and sometimes as a counterpart of the flowchart. [2] Flow diagrams are used to structure and order a complex system, or to reveal the underlying structure of the elements and their ...
The system diagram for representing control loops is a Piping and instrumentation diagram. Commonly used control systems include programmable logic controller (PLC), Distributed Control System (DCS) or SCADA. Example of level control system of a continuous stirred-tank reactor. The flow control into the tank would be cascaded off the level control.
The definition of a closed loop control system according to the British Standards Institution is "a control system possessing monitoring feedback, the deviation signal formed as a result of this feedback being used to control the action of a final control element in such a way as to tend to reduce the deviation to zero." [2]
Graphical system design (GSD) is a modern approach to designing measurement and control systems that integrates system design software with COTS hardware to dramatically simplify development. This approach combines user interfaces, models of computation , math and analysis, Input/output signals, technology abstractions, and various deployment ...
