A loosely coupled architecture for networked control systems

Nowadays the use of so-called Network Control Systems is a common practice. Although convenient, networks introduce several perturbations to the control system, due to the additional latency, jitter and even errors that arise when messages fail to be delivered. This paper presents a control architecture that attenuates the impact of the network on the controller performance. The proposed architecture is based on a series of data buffering and estimation, decoupling the controller execution from the instants in which messages are transmitted. In the sequel, important bandwidth are also attained, due to the batch transmission of sensor and control data.
