Flexible Time-Triggered Communication on a Controller Area Network
نویسندگان
چکیده
Controller Area Network is normally used in eventtriggered communication systems. These are known for not supporting composability with respect to the system temporal behavior. When using a time-triggered communication paradigm, such composability is achieved. However, common time-triggered systems rely on static message scheduling which compromises system flexibility. In this paper the authors study the possibility of using centralized scheduling together with a planning scheduler on a CAN system to achieve flexible time-triggered communication. Some preliminary results seem to validate the proposal but show an important influence of the low processing capability of the microcontroller used (80C592), which strongly limits the overall bus utilization factor.

The FTT-CAN protocol: why and how
The requirement for flexible operation is becoming increasingly important in modern industrial systems. This requirement has to be supported at all system levels, including the field level in process industry, as well as the cell and machine control levels in manufacturing industry, where fieldbus-based communication systems are commonly found. Furthermore, typical applications at these levels ...
متن کاملError Recovery in the Time-Triggered Paradigm with FTT-CAN
Data networks are naturally prone to interferences that can corrupt messages, leading to performance degradation or even to critical failure of the corresponding distributed system. To improve resilience of critical systems, time-triggered networks are frequently used, based on communication schedules defined at design-time. These networks offer prompt error detection, but slow error recovery t...

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
