Abstract
A method for a determination of the optimal duration of a time slot for computational actions in a time-triggered controller. The controller includes a sensor subsystem, a computational subsystem, an actuator subsystem, and a time-triggered communication system. The time-triggered communication system is placed between the sensor subsystem, the computational subsystem, the actuator subsystem, and a monitor subsystem. An anytime algorithms is executed in the computational subsystem. A plurality of execution slot durations of the anytime algorithms is probed during the development phase, starting from the minimum execution slot duration, increasing this slot duration by the execution slot granularity until the maximum execution slot duration is reached. In each of the execution slot durations, a multitude of frames is executed in a destined application environment. In each frame the computational subsystem calculates imprecise anticipated values of observable state variables by interrupting execution of the anytime algorithm at the end of the provided execution slot duration, using data received from the sensor subsystems at the beginning of the frame.
