Résumé
Keynote Speaker Enrico Bini, Scuola Sant'Anna, Pisa, Italy Real-Time Scheduling for Control Systems Schedulability analysis consists of performing a guarantee test to verify whether a given scheduling algorithm is able to execute a set of real-time tasks within their deadlines, assuming their values are known and given in advance. However, at a design stage, it is not always clear how task deadlines should be assigned to best meet the system requirements. Also, in Fixed Priority scheduling the process of assigning priorities is often driven by the relative "importance" of the tasks in the application. However, there may be very important tasks that could run with lower priority, as well as less important tasks that are sensitive to delay that would require to run at higher priority. The problem of assigning performance parameters (such as priorities, deadlines or periods) is that their effect is difficult to measure quantitatively in terms of application requirements. Control systems represent a case in which measuring the performance is possible and there are techniques that relate stability, speed of convergence, and sampling error to performance requirements. This talk presents an overview of the techniques that can be used to design control systems taking performance requirements into account since a design stage. Extending such methods to other application fields is also discussed.
