Stabilization analysis and implementation for MIMO NCS with time-varying delays

This paper is concerned with the design of output feedback controllers for a class of maximum input maximum output networked control systems (NCSs). In view of NCSs with many independent sensors and actuators, a discrete-time model with multiple time-varying delays is proposed. By constructing a novel Lyapunov-Krasovskii functional, a new less conservative stability criterion is developed in terms of linear matrix inequality. On the basis of the obtained stability condition, a static output feedback controller can be designed by applying an iterative algorithm. Both simulation and practical experiment results are given to show the effectiveness of the proposed method.
