output = error x [P + I/s + Ds/(0.064s + 1)]
Where:
error = reference - feedback
P = proportional gain = Pr 14.10
I = integral gain = Pr 14.11
D = differential gain = Pr 14.12
Therefore with an error of 100 % and P = 1.000 the output produced by the proportional term is 100 %. With an error of 100 % and I = 1.000 the
output produced by the integral term will increase linearly by 100 % every second. With an error that is increasing by 100 % per second and D = 1.000
the output produced by the D term will be 100 %.
