CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated control-system gain margin factor: solve current open-loop gain scale relation over the valid real-number domain stated below. The implemented relation is b=a/c, evaluated from gain margin factor, gain at instability threshold to produce current open-loop gain scale. Gain margin compares the multiplicative gain at the stability boundary with the current loop-gain scale. This page isolates current open-loop gain scale and verifies it in the original relationship. Use values evaluated at the phase-crossover condition and state whether the result is linear or decibel scale.
Inputs and valid domain
- gain margin factor must be a finite real number.
- gain at instability threshold must be a finite real number.
