Comparison of Gain and Phase Margin to Analayze the Stability of Second Order System Under Different Damping Conditions and Different Types of Controllers Under Control Actions

In this paper our aim is to know the stability conditions of second order systems under different damping conditions and same case of stability we have judged for the case of 4 different types of controllers. Several procedures are there to analyse the stability of a system but here we have used only root locus method to know the condition of stability and we have prepared a table of gain and phase margin to analyse stability in a deeper manner.
