To illustrate proportional plus rate control, we will use the same heat. of the inherent characteristics of proportional control, a residual offset error remains.

Example of Proportional Plus Rate Control.
WEEK 06: MODES OF CONTROL: PROPORTIONAL. Offset. The permanent difference between the setpoint and the control value. This phenomenon only.
For processes that can tolerate neither continuous cycling nor offset error, a proportional plus reset controller can be used. For processes that need improved.
