What is gain margin, phase margin, gain crossover frequency, and phase cross frequency? What is the practical use of these parameters?
Can you tell me about gain margin, phase margin, gain crossover frequency, and phase crossover frequency?
Sure! Gain margin and phase margin are stability measurements of a control system. Gain margin is the amount of gain that can be applied to the system without causing instability, while phase margin is the amount of phase shift that can be applied to the system without causing instability. Gain crossover frequency and phase crossover frequency are the frequencies at which the gain and phase margins are equal to zero, respectively.
