Network-Based Optimal Controller Design Based on QoS
Yue Dong · Acta Automatica Sinica · 2007
In NCSs (Networked control systems), the problem of optimal network controller design based on quality of services plays an important role. However, up to now, little work has been done in this field. A codesign model of network scheduling and controller design is presented in this paper, and a synthesis performance index is proposed to connect the controller design with the network characteristics. In order to optimize this index, the discrete linear quadratic regulator is utilized to finish the codesign of the network controller and network. Simulation results show that the proposed method is effective.
