WebJun 13, 2016 · Hence marginally stable. It's exactly the same mechanism as with a pole at s = 0. Would you agree that the output of such a system would increase linearly when excited by a step? – Matt L. Jun 13, 2016 at 7:04 Of course, an integrator has a linearly increasing step response. No doubt about it. WebMay 25, 2024 · Thus, the poles are in the imaginary axis, which are given by the roots of the auxiliary polynomial A ( s). Indeed, the poles are obtained by solving A ( s) = s 2 + b = 0 viz. s = ± b j. Hence, the mass-spring system is marginally stable.
