Abstract
The employment of networked control systems (NCSs), where control systems are interconnected by communication networks, is a major trend in modern industrial control applications. The network-induced delays are unavoidable in NCSs, and affect system performance significantly. In this paper, an LQR optimal controller is designed based on a time delay model of an NCS in order to compensate for such time delays. The control performance of the NCS is validated through a case study.
