چکیده
In systems with switching actuators persistent motions of different nature may occur, such as limit cycles, quasi-periodic and chaotic motions. In this contribution the nature of persistent motions in an attitude control system with switching actuators subject to switching restrictions are examined as a function of controller parameters. Bifurcation diagrams are used to describe observations. In the light of the bifurcation diagrams, control issues and earlier results obtained with the describing function method are assessed from a more general perspective. Copyright © 2005 IFAC

The current work presents an API based on the Real-Time Specification for Java (RTSJ) that optimizes real-time embedded systems development. Using this API it is possible to state non-functional specifications, like time constraints, and guarantee its implementation in the selected platform. Moreover, it discusses how real-time requirements derived from the RT-UML standard can be mapped to the ...
