摘要：
A Feedback Control method of Deadline Assignment (FC-DA) is presented to reduce output jitter of control tasks. The prevailing PID control law is employed, whose parameters can be adaptively adjusted online according to CPU load and jitter. The schedulability of whole task set is guaranteed dynamically. A simulation experiment shows the improvement when compared with proportional-only law.
