Modeling of a Type of Networked Cascade Control System
Congzhi Huang, Yan Bai, Xinli Li · 2008
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 transmission is derived and presented, taking into account data packet dropout. Future research directions on networked cascade control systems are also discussed.
