The concept of networked cascade control system, a cascade control system wherein the control loops are closed through a real-time network, is introduced, and the locations of the network in a type of networked cascade control system based on fieldbus are pointed out. Using the augmented state vector method, the closed-loop model of the overall system with single-packet transmission and multiple-packet...
Based on industrial process control practice, the concept of networked cascade control system is put forward. Four configurations of networked cascade control system are explicitly proposed and the advantages and disadvantages of each are presented and compared. Several issues induced by the network intersected in the control loops are analyzed, including the network-induced delay, data packet dropout,...
