Abstract
The increasing demand for mapping diverse embedded features onto shared electronic control units has brought about novel ways to co-design control tasks and their schedules. These techniques replace traditional implementations of control with new methods, such as pattern-based scheduling of control tasks and adaptive sharing of bandwidth among control loops through orchestration of their execution patterns. In the current practice of control design, once the static execution schedule is prepared for control tasks, no further control-related optimization is attempted for improving the control performance. We introduce, for the first time, an algorithmic mechanism that re-engineers a recurrent control task by enforcing switching between multiple control laws, which are designed for compensating the non-uniform gaps between successive executions of the control task. We establish that such post-processing of control task schedules may potentially help in improving the combined control performance of the co-scheduled control loops that are executing on a shared platform.
