Abstract

In cyber-physical systems, computing resources are often limited and overload situations may occur. For overload avoidance, job skipping is a useful and simple method. However, job skipping causes a state estimation error of a dynamic observer in an output-feedback controller. In this paper, we propose a modified observer so as to reduce it and maintain a control performance.
