Gain-Scheduling-Based State Feedback Integral Control for Networked Control Systems

This paper presents a new controller design method for networked control systems (NCSs), which is motivated by that static state feedback control (SSFC) shows an offset in the plant output when there is nonzero disturbance. Different from the existing SSFC results, the proposed method constructs a gain-scheduling-based state feedback integral controller, where an integral action is introduced to address the nonzero disturbance issue, and most especially, a gain scheduling strategy is employed to improve the control performance of NCSs. Moreover, the obtained results are also extended to the output feedback case. Simulation and experimental results are given to demonstrate the effectiveness of the proposed approach.
