This paper presents a framework for simulating the flight dynamics and control strategies of the fruit fly Drosophila melanogaster. The framework consists of five main components; an articulated rigid-body simulation, a model of the aerodynamic forces and moments, a sensory systems model, a control model, and an environment model. In the rigid-body simulation the fly is represented by a system ...

Amethod for generating a near-minimum-time control input for  exible structures is presentedwith the objective of minimizing the maneuver time and the residual energy of the  exible modes. The method is based on smoothing the bang–bang, time-optimal control input designed for the rigid-body mode. Smoothing is accomplished through the addition, to the basic time-optimal control problem for the...

Fuel efficiency, endurance, and noise requirements are pushing modern aircraft to lighter, more flexible designs. This causes the structural modes to occur at lower frequencies increasing the coupling with the rigid body dynamics. The traditional approach to handle aeroservoelastic interaction is to design gain-scheduled flight control laws based on the rigid body dynamics and then use filters ...

in this paper, a simple and efficient method for modeling and solving the equations of a rotor with any number of disks, bearings and mass unbalances is presented using the assumed modes method. this model consists of a continuous shaft, arbitrary number of mass unbalances in any axial location and phase angle, and any number of rigid disks and bearings. this arrangement is extensively used in ...

A discrete-cosine-transformation (DCT) based decomposition method is proposed for modeling part form error, which decomposes the error field into a series of independent error modes. Compression, which ensures a compact model, is achieved by correlation reduction or mode truncation based on good energy compaction property of DCT. The part error related to assembly process (rigid body modes) and...
