Nonlinear stability and post-critical analysis of an uncertain plant with describing functions and integral quadratic constraints

Nonlinear Robust Approaches to Study Stability and Postcritical Behavior of an Aeroelastic Plant

“…In the IQC approach, conservatism of the analyses due to the multipliers' selection is investigated and some heuristics are discussed in view of its acknowledged effect on the accuracy of the results [17]- [19]. Preliminary results of the studies discussed in this work were presented in [20].…”
