Feedforward control is based on principle of pre-emptive load counter-action i.e. if all major loads (i.e. disturbances) on a process…
We know very well that closed loop control provides increased performance over open loop control. So it would be rational…
The ladder diagrams are universally used as a symbolic and schematic way to represent the interconnection between the elements in…
This is a control system that manages a process defined by a series of tasks to be performed i.e. a…
In distributed control system, each process has its own separate controller located at the site. These local controllers are interconnected…
Process control can be defined as a control system that manages a particular industrial process so that a uniform, correct…
The goal of most electronic systems is to measure or control some physical quantity. The system will have to acquire…
Proportional-Integral-Derivative For processes that are able to operate with continuous cycling, the relatively inexpensive two position controller is sufficient. For…
This type of control is combination of two control modes, proportional and integral (reset). The Combining of the two modes…
Valves cannot control a process by themselves. Manual valves require an operator to position them to control a process variable.…
