WebExample. Determine the gain margin and the phase margin for a system that gave the following open-loop experimental frequency response data: at frequency 0.005 Hz a gain of 1.00 and phase −120°, at 0.010 Hz a gain of 0.45 and phase −180°.. The gain margin is the factor by which the gain must be multiplied at the phase crossover to have the value 1. WebWhen the phase shift passes across 360° (or 0° in a Bode plot), the gain is designed to be more than 15 dB, another condition - for a stable system. Obviously, the 90° from the compensation is adjustable value the an at design stage to … Web\$\begingroup\$ Gain margin and phase margin are both used in assessing relative stability of the closed loop, based on open loop metrics. The gain margin is the negative value of gain (dB) at the frequency where the open loop phase angle is -180 degrees (= phase … other word for business owner
