FROM HYBRID SYSTEM SIMULATION TO REAL-TIME IMPLEMENTATION

Scicos is a hybrid system simulator. In the context of automatic control, such systems are usually obtained by interconnecting a model of the environment with the model of the controller. Simulation is used to validate the controller which is usually designed using a simplified model of the environment. But even if the controller does perform properly during simulation, there is no guarantee that it can actually be used. For that, the controller algorithm must be implemented on the available hardware and satisfy the real-time constraints. SynDEx is a specialized software used for optimized real-time implementation on multiprocessor architectures. ScicosSynDEx interface provides an environment in which controller implementability can be easily tested and controller parameters adjusted iteratively, if necessary; not to mention the generation of the real-time code for the controller hardware. This interface not only speeds up the design process, but also assures that the real-time code has the same properties as the controller model used for the simulation.
