Static Output Feedback Stability Analysis and Synthesis for MIMO NCS with Time-varying Delays

摘要

This paper is concerned with the design of output feedback controllers for a class of MIMO 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.A numerical example is given to show the effectiveness of the proposed method.
