Abstract
A major trend in modern aerospace and automotive systems is to integrate computing, communication and control into different levels of the vehicle and/or its supervision. A well fitted architecture adopted by this trend is the common bus network architecture. A Networked Control System (NCS) is called when the control loop is closed through a communication network. The presence of this communication network introduces new characteristics (sharing bus, delays, jitter,etc) to be considered at design time of a control system. This work focuses on the effect of sharing bus between the control system and the other devices connected to the bus foreigner to control. These last devices are called interferences. We intented to show, through simulations, the influence of sharing bus on real time control systems performance. To compare effects, we choose the CanBus protocol where the medium access control is event driven; and the TTP protocol where the medium access control is time driven. In the future, we intent to extend this study to the Attitude and Orbit Control System (AOCS) of Multi-Mission Platform (MMP) satellite in its nominal operation mode.
