Abstract
A method of controlling a system includes the steps of launching a task having associated therewith a worst case execution time, and monitoring the end of the task after the end of a time slot allocated to the execution of the task, wherein the time slot is shorter than the worst case execution time. The task may be launched periodically according to a fixed period of time, and when the execution of the task ends before the allocated time slot, the method may further include outputting a value calculated based on a current input value but when the execution of the task does not end before the allocated time slot, the method may further include outputting a value calculated based on a previous input value and stopping the task and launching the task again at the next period of time with a next input value.
