Real-time control algorithms are designed based on the
characteristics of the controlled plants and they require good
performance without delays. However, digital control implementation
typically introduces delays and jitters due to insufficient CPU
processing power and the limitations of the real-time scheduling
method used. This can degrade the system performance or even make it
unstable.
In this paper we propose an integrated approach for control design
and real-time scheduling, suitable for both discrete-time and
continuous-time controllers. It guarantees system performance by
accepting a certain minimum value of jitter for control tasks and
feasibly schedules them together with other tasks in the system.
Results from comparison with other approaches from real-time and
control theory domains underline the effectiveness of our method.
