Gain of control system
WebFrom Equation 2, we can say that the overall gain of negative feedback closed loop control system is the ratio of 'G' and (1+GH). So, the overall gain may increase or decrease … WebA good stable control system usually has an open-loop gain significantly less than 1, typically about 0.4–0.5, when the phase shift is −180° and so a gain margin of 1/0.5–1/0.4, i.e. 2–2.5. 3. Gain crossover This is the frequency at which the open-loop gain first reaches 1. 4. Phase margin
