Process Controls
Summary
The PID control mode is summarized below.
Proportional Plus Reset Plus Rate Control Summary
The PID controller combines the three individual modes to achieve the
advantages of each.
The proportional action responds to the error amplitude.
The integral action eliminates the offset error.
The derivative action provides additional stability to the process.
PID controllers can be used to control most processes, even those that are
difficult to control.
