Feedback scheduling for real-time control of systems with communication delays

This work is devoted to integrated control-scheduling in the case of real-time control of systems with communications delays, i.e. network induced delay and input output latency. Feedback control of computing resources is tackled, to deal with CPU resource variations and unpredicitble workload. Thus two new control schemes are provided for feedback scheduling of single and multi control task systems. Moreover the system control design takes into account the unknown delays due to the temporal uncertainties that are unavoidable in real-time control. A new method of state feedback control design for discrete time-delay systems is presented in a LMI formulation. Two illustrative examples show the interest of the proposed approach.
