چکیده

As airframe become more and more complex, and are called upon to perform increasingly stre~sful maneuvers, autopilots must be robust enough to adequately stabilize the airframe in the highly non-linear, strongly cross-coupled environments. Classic autopilot design can achieve stability throughout he flight envelope, but generally lack robustness for design and environmental ehange.~. Guidance and control routines composed of a neural net architecture offer a promising ability to process multiple inputs, generate the appropriate outputs, and provide greater robustness. However, difficulty can arise in the training proce,~ of the neural nets. In the present study, a feedforward neural net wa~ used for the guidance and control routine.~ on typical airframe.~. The neural nets were trained through genetic algorithms. The work attempt~ to model the biological process of the "’thinking" aspect of the airframe.~ by the u~ of a neural nets trained through natural ~lection a~ put forth in the Theory of Evolution. The pre~nt study produced an autopilot that learned to control it~ rates and maneuver (with a full six degree.~-of-freedom) across an arena to a target.

Numerical and Neural Network Modeling and control of an Aircraft Propeller

In this paper, parametric and numerical model of the DC motor, connected to aircraft propellers are extracted. This model is required for controlling trust and velocity of the propellers, and consequently, an aircraft. As a result, both of torque and speed of the propeller can be controlled simultaneously which increases the kinematic and kinetic performance of the aircraft. Parametric model of...

Modeling and Multi-Objective Optimization of Stall Control on NACA0015 Airfoil with a Synthetic Jet using GMDH Type Neural Networks and Genetic Algorithms

This study concerns numerical simulation, modeling and optimization of aerodynamic stall control using a synthetic jet actuator. Thenumerical simulation was carried out by a large-eddy simulation that employs a RNG-based model as the subgrid-scale model. The flow around a NACA0015 airfoil, including a synthetic jet located at 10 % of the chord, is studied under Reynolds number Re = 12.7 × 106 a...

Aircraft Visual Identification by Neural Networks

In the present paper, an efficient method for three dimensional aircraft pattern recognition is introduced. In this method, a set of simple area based features extracted from silhouette of aerial vehicles are used to recognize an aircraft type from its optical or infrared images taken by a CCD camera or a FLIR sensor. These images can be taken from any direction and distance relative to the fly...
