Optimal inversion-based control for the set-point regulation of nonminimum-phase uncertain scalar systems. (English) Zbl 1009.93024

The paper presents an optimal inversion-based control for the set-point constrained regulation of nonminimum-phase uncertain scalar systems. The proposed solution is based on a new architecture where the main purpose of the feedback is to reduce the sensitivity to parametric plant uncertainties permitting in such a way the effective use of a feedforward action determined via a stable dynamic inversion. This new control scheme permits obtaining high performance as can be easily seen by a worked example.
