Abstract
We show that stabilizing tracking proportional-integral (PI)
controllers can be constructed for minimum-phase nonaffine-in-control
systems. The constructed PI controller is an equivalent realization of
an approximate dynamic inversion controller. This equivalence holds
only for the time response when applied to the unperturbed system.
Even when restricted to unperturbed minimum-phase linear time invariant
systems, their closed loop robustness properties differ. This
shows that in general, properties that do not define the equivalence relation
for systems/controllers are not preserved under such equivalence
transformations.
