1. MODERN AIRCRAFT BRAKING SYSTEMS.

Author

Subjects
BRAKE systems, ACTUATORS
Abstract

This paper presents some problems concerning the present trends in the field of aircraft braking systems. New solutions like electro-mechanical or electro-hydrostatic actuators are considered the future, but some big aircraft producers do not renounce yet to classical electro-hydraulic braking systems. New solutions are not generally accepted, they have to prove their reliability and that they bring considerable more advantages than penalties. [ABSTRACT FROM AUTHOR]

Abstract

This paper presents a study concerning a canard UAV improvement using vectored thrust. There are taken into account the take-off and landing behavior. Vectored thrust can extent the attack angle range for a canard UAV, and so, one can decrease the take-off and landing speeds and also the take-off and landing distances. [ABSTRACT FROM AUTHOR]

Abstract

In this paper one presents a model and an analysis of a dc-to-dc Buck converter, in closed loop, from 24V to 12 V with a power of 500 W. Model is implemented in MATLAB/SIMULINK toolbox SIMPOWERSYS. Control system is a fuzzy logic one, Mamdani type, and using P.I. configuration. One opted for a fuzzy controller due to its flexibility in its configuration and tuning process, and also because it doesn’t need to know a mathematical model for the Buck converter. Fuzzy controller is composed of two sub-controllers in parallel, one for the proportional component and a second for integrative component. One proposes this configuration because fewer inference rules are necessary and also the tuning process is easily accomplished compared to a fuzzy controller with two inputs. Implemented model is validated by numerical simulations and the results are realistic and confirm the possibility to use this type of controller. [ABSTRACT FROM AUTHOR]
