Generally in a root locus plot, when the system has a pole and a zero, both complex, it generates arc-shaped path between them, tending to the upper side.
The topics include dynamic response and the Laplace transform method, spring and damper elements in mechanical systems, fluid and thermal systems, control system design and the root locus plot, and vibrator applications.
The open loop poles of the transfer functions corresponding to the dynamics described in (1) and (2) are shown by means of root locus plots in Fig.
