To illustrate the concept of offset, refer to the following waveform. When the feedback has
stabilized, it is not equal to input command. In this case, the difference between the input
command and the feedback is the offset. Note that the integral gain is set to zero.
Feedback
Input Command
(Oscilloscope set to:
vertical=1 V/ division
horizontal=1.0 sec/division
Gain Settings:
Proportional gain=25
Integral gain=0.00 Hz
Offset
The next waveform illustrates what happens when the proportional gain is increased from
25 to 100. An increase in the proportional gain causes the controlled variable to respond
more quickly as indicated by the feedback signal.
