Predictive control of a Boeing 747 aircraft using an FPGA

New embedded predictive control applications call for more eficient ways of solving quadratic programs (QPs) in order to meet demanding real-time, power and cost requirements. A single precision QP-on-a-chip controller is proposed, implemented in afield-programmable gate array (FPGA) with an iterative linear solver at its core. A novel offline scaling procedure is introduced to aid the convergence of the reduced precision solver. The feasibility of the proposed approach is demonstrated with a real-time hardware-in-the-loop (HIL) experimental setup where an ML605 FPGA board controls a nonlinear model of a Boeing 747 aircraft running on a desktop PC through an Ethernet link. Simulations show that the quality of the closed-loop control and accuracy of individual solutions is competitive with a conventional double precision controller solving linear systems using a Riccati recursion. © 2012 IFAC.

Investigating landing gear noise using fly-over data: The case of a Boeing 747-400

Modeling the noise originating from a landing gear has proven to be a challenging task, because of its complicated structure. In full-scale, landing gear noise can only be investigated experimentally by source localization techniques and fly-over measurements with microphone arrays. In the present work, measurements of a Boeing B747-400 were used to determine the contribution of the landing gear to the overall noise emitted during a fly-over and how the broadband noise from the landing gear scales with the flight velocity. A tonal source from the nose landing gear was identified at 380 Hz with a harmonic at 760 Hz and it most likely originates from a cavity. It was also found that the Power Spectral Density (PSD) of the high frequency broadband component varies linearly with frequency and there is some scaling with the ow velocity. Finally, the nose landing gear was shown to be a significant contributor to the overall airframe noise as expected.

Poética e Figuratividade: uma análise de Io (Ovídio, Metamorfoses, I, 583-747)

This paper presents the development of a scientific investigation that addresses the Latin text using theoretical concepts of Linguistic, Literary Poetic and Semiotic in order to focus mainly on aspects of the figurative expression. Therefore, the meaning effects raised by the perception through the reading of text were taken as baseline data to investigate the particular arrangement of language, responsible for expression of these effects. As a result of this investigation, a metalinguistic discourse was produced about the basic features of the poetic figurativity of the text. This analysis and description had a focus mainly on the first step of the procedures of figurativization, i.e., the figuration of the discourse, when a theme is coated by semiotic figures. In addition, reference notes were drafted to accompany the selected translation of support, with general comments about the culture (mythology, history, geography, philosophy, etc.), necessary data to an more comprehensive understanding of the text (these notes shall provide basic subsidies for reading the original Latin)
