Optimal combination of forward error correction and selective state feedback for wireless feedback control systems

Abstract

In wireless feedback control systems, loss of control packets due to unreliable wireless channels is one of the most important problems. To cope with this problem, we have proposed a novel concept that combines forward error correction (FEC) and selection of important state feedback while keeping a fixed packet length. In this paper, we provide its optimization based on a control layer's theorem. Numerical results show that the proposed method can achieve the best control performance against communication channel errors.
