The application of nonlinear inverse dynamics for aircraft control at high angles of attack

Złocka M.

Research Bulletin / Warsaw University of Technology, Institute of Aeronautics and Applied Mechanics

1999

nr 9

179-184

The main objective of this work is the elimination of the wing-rock phenomenon during the aircraft motion at high angles of attack. Two wing-rock models having three or one degree of freedom are considered. In the paper, the nonlinear control laws have been synthesised for stabilization of the steady horizontal motion of the aircraft. The synthesis is based on the nonlinear inverse dynamics. As an example the numerical simulation of the controlled motion is carried out employing the aerodynamic and mass data of the F-16 aircraft.

Uncertainty management methods and tools with applications to aircraft flight control system design

Brusov V., Tiumentsev Y.

Research Bulletin / Warsaw University of Technology, Institute of Aeronautics and Applied Mechanics

Almost all kinds of men's activities associated with design, manufacturing and maintenance of complex systems consist of next two main classes of problems: a generation of decision alternative set allowed for situation studied, and decision making, i.e. choice of some decision alternative from the set of allowed ones. A role of various kinds of uncertainties related to complex system design process is discussed based on intelligent flight control system design example. A mixed information technology is used for this problem solving based on mathematical modeling, multi-purpose system methodology and artificial neural networks. This approach promises to stay an effective technical decision generation and making tool for problem solving with various kind of uncertainties involved.
