Ultimate gain method
Web1 Jul 2024 · The term ultimate gain was attached to this method because its use require the determination of the ultimate gain (sensitivity) and ultimate period. The ultimate … WebThis mode determines the speed of response for the loop. The higher the controller gain, the faster the loop responds. However, higher controller gains lead to overshoot and oscillations in the response. For each loop, there is a maximum value of the controller gain, known as the ultimate gain, for which the loop is stable. Integral.
