Abstract:
We study the stability of a one-channel two-mass system controlled by a proportional integral differential (PID) controller. The controlling force is applied only to one of the masses and the output is the deviation of this mass. It is shown that, among PID controllers, the greatest stability is provided by the regulators for which the right vertical of the roots of the characterisitc polynomial contains a complex pair of multiplicity 2.
