Fuzzy logic is a human model, potentially applicable to a wide range of processes and tasks that require human instinct…
Transfer Functions A transfer function is a mathematical formulation that relates the output variable of a device to the input…
The diagram below shows a digital control system for a drill press that includes: the input, digital processor, drill-positioning mechanisms,…
The block diagram below illustrates the basic elements of a minicomputer system for speed and voltage control as well as…
Before we discuss how to tune the PID controller, let’s look at some basic facts about PID Controller. Basic Facts…
In some processes, it is a common requirement for two flows to be kept in precise ratio to each other…
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…
Proportional-Integral-Derivative For processes that are able to operate with continuous cycling, the relatively inexpensive two position controller is sufficient. For…
Proportional plus derivative (rate) control is a control mode in which a derivative section is added to the proportional controller.…
