A clamped rotating thin-walled composite elastic blade subjected to periodic base excitation
is considered in this paper. The mathematical model of the structure captures the complex …

Abstract μ analysis is one of the most efficient techniques to evaluate the stability margins
and the performance levels of linear time-invariant systems in the presence of structured …

A general approach to analyze the robust performance and robust stability via the worst-
case input/output gain for uncertain, linear time periodic systems is presented. The …

This paper presents a detailed comparison of the most significant methods developed to
compute lower bounds on the structured singular value. The objective is to characterize the …

This paper evaluates the effects and effectiveness of a dynamic vibration absorber (DVA)
designed for mitigation of unstable oscillations of helicopters when it is on the ground, ie …

Ground Resonance (GR) in helicopters is a potentially catastrophic instability defined in
certain rotor speed ranges. It can limit the helicopter operational envelope and become the …

This paper presents the parametric uncertainties identification of a robotic system of one
degree of freedom. A MSC-ADAMS/MATLAB co-simulation model was built to simulate the …
