Micro air vehicles (MAVs) have wide application prospects in environmental monitoring,
disaster rescue and other civil fields because of their flexibility and maneuverability …

In this paper we show how higher-order averaging can be used to remedy serious technical
issues with the direct application of the averaging theorem. While doing so, we reconcile two …

Winged insects vary greatly in size, from tiny wasps (0.015 mg) to large moths (1.6 g).
Previous studies on the power requirements of insect flight focused on relatively large …

This paper discusses the effects of wing inertial forces on flight stability and required lift for
hovering of insects with a varying stroke plane. In this paper, the stroke plane of a flying …

The dynamic modelling and attitude controller design of a flap** wing aircraft, Beihawk,
were investigated in this study. The aircraft features of an X-shaped flap** wing …

Flap** flight dynamics is quite an intricate problem that is typically represented by a multi-
body, multi-scale, nonlinear, time-varying dynamical system. The unduly simple modeling …

The complex dynamics characterizing deformable terrain presents significant impediments
toward the real-world viability of locomotive robotics, particularly for legged machines. We …

This paper demonstrates the extension of the harmonic decomposition methodology,
originally developed for rotorcraft applications, to the study of the nonlinear time-periodic …

Geometric control theory is the application of differential geometry to the study of nonlinear
dynamical systems. This control theory permits an analytical study of nonlinear interactions …

Differential-geometric-control theory represents a mathematically elegant combination of
differential geometry and control theory. Practically, it allows exploitation of nonlinear …
