And Control

The article presents the project of UAV control system realized at Department of Avionics and Control Systems of Rzeszów University of Technology. The project is based on earlier experiences. In the article general structure of the onboard control system is shown as well as the structure of control station. There are described in proposed control and navigation procedures as well as human factor, failure detection and system reconfiguration.

Aerospace plane, the next generation manned spacecraft has the characteristics of high reliability and high security. Therefore, a five modular redundancy byzantine fault tolerant architecture is propose for the guidance, navigation and control (GNC) system. This architecture can give the system characteristic of double fault resilience, and is also suitable for solving Byzantine general problem. A semi-physical simulation is done, which is based on 1553B data bus and VxWorks operating system. The simulation result has verified the fault tolerant architecture and feasibility of the system implementation.
