Abstract : With the wide development of microsystems, it is likely that they will be massively used in critical control systems. This raises many new challenges, among which the definition of a dependable communication network with high integrity level.
The study of standard communication networks and their basic commonly used transmission errors detection techniques based on CRC codes shows that they cannot ensure the required integrity level.
To reach this integrity level, we propose an original solution - an evolutive error control function - based on the slowly evolution characteristic of the control systems considered, for which the integrity is considered for a set of consecutive messages and not for a single message. The validation of the proposed solution is based on MATLAB simulation models we have developed.
The study case is about the integration of thousands of micro-surfaces such as micro-spoilers in future flight control systems.
