This paper presents a resource management strategy for
control tasks that maximizes control performance within the
available resources by readjusting the task periods at runtime.
A feedback scheduler is used to determine on-line
the optimal task periods considering the response over a finite
time horizon of the plants controlled by arbitrary linear
control laws. We show how this problem can be expressed
as an optimization problem, where the objective function
relates the sampling periods to the transient responses of
the controlled plants, and where restrictions are based on
EDF schedulability constraints. For the general case, the
solution of the optimization problem is computationally expensive,
and thus, an approximate procedure to be executed
on-line has been developed. We present simulation results
that validate the presented approach.
