In this paper, global optimisation and nonlinear simulation are used to search for the worst-case control demands which may be input by a pilot flying a modern high performance aircraft with a full authority flight control law. The flexibility of global optimisation is exploited to simultaneously search for worst-case pilot inputs and worst-case combinations of uncertain parameters in the nonli...

OBJECTIVE This study investigated whether stress training introduced during the acquisition of simulator-based flight skills enhances pilot performance during subsequent stressful flight operations in an actual aircraft. BACKGROUND Despite knowledge that preconditions to aircraft accidents can be strongly influenced by pilot stress, little is known about the effectiveness of stress training a...

Future aircraft generations are required to provide higher performance and capacity with minimum cost and environmental impact. This fact calls for the design of revolutionary unconventional configurations, such as the Blended Wing Body (BWB), a tailless aircraft which integrates wing and fuselage into a single lifting surface with efficient and promising results. In this paper, a BWB aircraft ...

This article presents an adaptive backstepping approach to the longitudinal (γ, α,Q) control of an aircraft that directly accommodates magnitude, rate, and bandwidth constraints on the aircraft states and the actuator signals. The article includes design of the control law, Lyapunov analysis of the stability properties of the closed loop system, and simulation based analysis of the performance.

Due to the large increase in the density of aircraft arrivals at airports in recent years, it has become important to optimize the scheduling of aircraft landings in order to reduce wait time, improve airport efficiency, and minimize fuel consumption while maintaining safety. As the density of aircraft arrivals increases, however, so too does the complexity of trajectory planning and generation...

Active control techniques for the gust loads alleviation/flutter suppression have been investigated extensively in the last decades to control the aeroelastic response, and improve the handling qualities of the aircraft. Nonadaptive feedback control algorithms such as classical single input single output techniques (Schmidt & Chen, 1986), linear quadratic regulator (LQR) theory (Mahesh et al., ...

paper presented below is analysis of fuzzy logic controller is carried out and proven that it is best suitable for autopilot system design. Modern day aircrafts heavily rely on automatic control systems for most of the functions and there is always a persistent demand for efficient controllers. There are already many control techniques and methods developed in the field of control engineering, ...

Backstepping is one of the most promising advanced control laws developed for xed-wing Unmanned Aerial Vehicles (UAVs). Its nonlinearity combined with adaptation guarantees adequate performance over the whole ight envelope even when the aircraft model is not exact. In the literature, there are several attempts to apply a backstepping controller to aspects of xed-wing UAV ight. Few of them attem...

This paper presents an investigation into the controllability for an aircraft of seamless aeroelastic wing. The research is aimed at the design of control laws for the aircraft rolling by actively operating a pair of an unconventional hingeless flexible leading and trailing control surfaces at different flight speed. The main challenge is how to achieve a specified rolling rate for the aircraft...

In the 21 st Century, reducing the environmental impact of aviation will become an increasingly important priority for the aircraft designer. Among the various environmental impacts, emission of CO2 can be expected to emerge as the most important in the long term and reducing fuel burn to become the overriding environmental priority. Increasing fuel costs and the world’s limited oil reserves wi...
