Networked control system with asynchronous samplings and quantizations in both transmission and receiving channels

This study addresses a problem of the controlling networked control systems (NCSs) which is consisted of the continuous-time plant and controller. In both transmission and receiving channels, asynchronous sampling and different logarithmic quantization effects are considered. By categorizing three cases of asynchronous sampling and using two properties of quantizer which are sector bounded and convex combination, sufficient conditions of the existence of desired controllers for each asynchronous case are presented in the form of linear matrix inequalities (LMIs). Simulation results are given to illustrate the validity of the proposed methods.
