WebOct 1, 2024 · The dynamics of any control loop are governed the components involved. The purpose of "compensation" is to avoid building an oscillator from an amplifier. This can happen when the loop gain exceeds unity AND the phase shift is any multiple of 360°. This is usually accomplished by adding phase shift in the vicinity of the unity gain crossover. N.B.
