Abstract
In recent years, there has been increasing interest in controlling systems over communication networks because communication networks are among the fastest-growing areas in engineering. Networked control system (NCS) is a feedback control system wherein the control loops are closed through a computer network. Such systems offer advantages such as lower installation costs, increased flexibility and rapid installation. However, communication delay is a general problem in NCS, and it could destabilize the closed-loop system. In this paper, controller structure is provided for NCS with constant delay and plant uncertainties. Our formulation and solution method utilize robust control design. We apply the proposed control strategy on a specific example testing with hardware-in-the-loop simulation using dSPACE DS1104 controller board for controlling a modular servo system. ©2006 IEEE.
