A Hierarchical Approach to Adaptive Control for Improved Flight Safety
Following failures of primary aerodynamic actuators, safe flight can be maintained by introducing alternative actuation systems, such as secondary aerodynamic surfaces and propulsion, for critical stability and control augmentation. This paper presents an intelligent hierarchical flight control system architecture that is designed using nonlinear adaptive synthesis techniques and on-line learni...
متن کاملReliability Analysis of Aircraft Servo-Actuation Systems Using Evidential Networks
Servo-actuation system is one of the key executing subsystems of the flight control system of an aircraft. With the development of fly-by-wire control systems, redundant servo-actuation systems have been extensively applied. A servo-actuation system has a long life and high reliability, which results in the lack of failure information. In the mean time, available data is insufficient and imprec...
متن کاملFlight Test Experience with an Electromechanical Actuator on the F-18 Systems Research Aircraft
Development of reliable power-by-wire actuation systems for both aeronautical and space applications has been sought recently to eliminate hydraulic systems from aircraft and spacecraft and thus improve safety, efficiency, reliability, and maintainability. The Electrically Powered Actuation Design (EPAD) program was a joint effort between the Air Force, Navy, and NASA to develop and fly a serie...
متن کاملDynamics, Control, and Stabilization of Turning Flight in Fruit Flies
Complex behaviors of flying insects require interactions among sensory-neural systems, wing actuation biomechanics, and flapping-wing aerodynamics. Here, we review our recent progress in understanding these layers for maneuvering and stabilization flight of fruit flies. Our approach combines kinematic data from flying insects and aerodynamic simulations to distill reduced-order mathematical mod...
متن کاملModelling of Flight Control Hydraulic Actuators Considering Real System Effects
The study investigates the effects of servo valve nonlinearity, actuation compliance and friction related nonlinearity on the dynamics of a flight control surface, during its deployment through an electro-hydraulic actuation system. Starting from the pilot command, a realistic model of the electro-hydraulic actuation system is evolved, which includes the command lags, servo valve nonlinearity, ...
متن کاملAn Integrative Model of Insect Flight Control
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 ...
