Definition of “P” (Proportional gain)
Proportional gain is the amplification that is applied to the process error signal, which will
result in a particular control output.
Proportional gain is mathematically defined as;
A
out
= K
p
Where;
A
out
= Control output
K
p
= Proportional gain
= Error signal = (Input Command - feedback)
In Figure 6-2 we see that the amplitude of the output of the control is dependent on the
error, multiplied by the proportional gain.
For a given amount of error, the greater the proportional gain, the greater the output.
It is also true that, for a given amount of proportional gain, the greater the error, the
greater the output.
