On-Line Safe Flight Envelope Determination for Impaired Aircraft

The design and simulation of an on-line algorithm which estimates the safe maneuvering envelope of aircraft is discussed in this paper. The trim envelope is estimated using probabilistic methods and efficient high-fidelity model based computations of attainable equilibrium sets. From this trim envelope, a robust reachability analysis provides the maneuverability limitations of the aircraft thro...

Dynamic Envelope and Control Shading Pattern to Visual Comfort of Office Building in Tehran

This work reviews the effect of parametric programming on visual performance, daylighting and shading in office buildings in Tehran-Iran and studies their influences that help not only to reduce the glare but also to promote useful daylight illuminance through promoting visual comfort. It starts by establishing a review of the effective parameters on visual comfort indices, glare indices, and d...

Envelope Theorems in Dynamic Programming

The Envelope Theorem is a statement about derivatives along an optimal trajectory. In Dynamic Programming the Envelope Theorem can be used to characterize and compute the Optimal Value Function from its derivatives. We illustrate this here for the Linear-Quadratic Control Problem, the Resource Allocation Problem, and the Inverse Problem of Dynamic Programming.

Aerodynamic Envelope Protection using Hybrid Control 1

Claire Tomlin, John Lygeros, and Shankar Sastry Department of Electrical Engineering and Computer Sciences University of California, Berkeley, CA 94720-1772 clairet, lygeros, [email protected] Abstract This paper presents the application of controller synthesis for hybrid systems to aerodynamic envelope protection and safe switching between ight modes. Each ight mode, which describes a c...
