Adaptive control for linear parameter-varying systems with application to a VTOL aircraft

Steven Snyder et al.

Summary: This paper presents design and analysis of an adaptive control architecture for LPV systems subject to time-varying parametric uncertainties and external disturbances, with both transient and steady-state performance guarantees. The approach introduces new tools and techniques for stability and performance analysis, potentially yielding less conservative results compared to previous methods.
