View source for What do you mean by "gain" in the speed control example? What relation to sensing does it have?

In this example, we let the engine force, <math>F_\mathrm{eng}</math>, be proportional to <math>(v_\mathrm{des}-v)</math>. The "gain" is the proportionality constant <math>k_p</math>. The use probably follows from that in [http://en.wikipedia.org/wiki/Gain electronic amplifiers].

We do not consider sensing problems in this example. Instead we assume perfect sensing/measurement of the output, which is the vehicle's velocity, <math>v</math>. The gain is only related to the control law.
