A priori stability conditions for an arbitrary number of unstable poles

Journal article

Necessary and sufficient stability conditions that place bounds on the current inputs are derived that guarantee BIBO stability and retain the control authority needed to asymptotically stabilize a system that is subject to physical input constraints. For open-loop stable systems, the stability conditions coincide with the physical constraints, but for unstable systems, tighter limits may be required. Use of these limits in a supervisory role with controllers that have no stability guarantee is discussed and illustrated. Copyright © 1996 Elsevier Science Ltd.
