– thermostat – chemical plants with valves, pumps – control modes for complex systems, eg. intelligent cruise control in automobiles, aircraft autopilot modes • Coordinating processes: systems which are comprised of many interacting subsystems (called multiple agent, or multi-agent systems) typically feature continuous controllers to optimize performance of individual agents, and coordination a...

Two preliminary studies explored differences in language and style between the design perspective and the operational perspective of autoflight systems. In the first study, responses of an expert pilot and an expert engineer to a set of incident reports involving an autoflight system were compared. In the second study, chapters describing an autoflight system in the system manufacturer's manual...

Matthes and Uustalu (TCS 327(1–2):155–174, 2004) presented a categorical description of substitution systems capable of capturing syntax involving binding which is independent of whether the syntax is made up from least or greatest fixed points. We extend this work in two directions: we continue the analysis by creating more categorical structure, in particular by organizing substitution system...

In this contribution the automated generation of LFT-based parametric uncertainty descriptions from a generic nonlinear aircraft-dynamics model, as used for the GARTEUR RCAM Design Challenge on Robust Flight Control, is described. For this purpose an object-oriented, equation-based modeling approach using the modeling environment Dy-mola was applied. Using this technique allows the modeling of ...

The power and speed of modern digital computers is truly astounding so that it enables carrying on complex tasks such as aerospace simulation, design and analysis, precisely. In addition to the nature of the guidance problem, the design technique, neural networks, necessitates cumbersome computations to yield precise and accurate performance. Neural networks approach the solution of this proble...

This paper presents an application of the nonlinear optimal control techniques to the design of launch vehicle autopilots. The optimal control is given by the solution to the Hamilton-Jacobi-Bellman (HJB) equation, which in this case cannot be solved explicity. A method based upon Successive Galerkin Approximation (SGA), is used to obtain an approximate optimal solution. Simulation results invo...
