Control system and elastic scheduling co-design

As the control systems´ dynamic property and the high requirement for real-time, the traditional real-time scheduling algorithms cannot adapt to the control system. Fortunately the adaptive closed-loop real-time scheduling algorithms behave robustly for disturbances. This paper discusses a new feedback real-time scheduling algorithm which can adapt to the special requirements of control system. The aim of this algorithm is to guarantee the QoC (Quality of Control) and to increase the reliability of control system. It allocates resource to tasks according their contribution to QoC. The scheduling algorithm and control system co-design involves how to assign the properties of real-time tasks. Take the CNC system as an example, this paper also represents the method of scheduling algorithm and control system co-design.
