The damping ratio is a parameter, usually denoted by ζ (Greek letter zeta), that characterizes the frequency response of a second-order ordinary differential equation. It is particularly important in the study of control theory. It is also important in the harmonic oscillator. In general, systems with higher damping ratios (one or greater) will demonstrate more of a damping effect. Underdamp… WebThe natural frequency and damping ratio of a system have been defined in the solution template as the variables wn and zeta, respectively. Assuming the transfer function has …

WebThis area generally defines a regio where the damping ratio of the system belongs the interval ζ < 0.5. So if you want your damping ratio to be exactly ζ = 0.5 you need to place your poles exactly on the diagonal lines where the lines cross the root locus graph (the poles of the closed loop system are noted with a pink o ).
