| Abstract: |
| This paper studies the problems of H-infinity performance optimization and controller design for continuoustime
NCSs with both sensor-to-controller and controller-to-actuator communication constraints (limited communication
channels). By taking the derivative character of network-induced delay into full consideration and defining new Lyapunov
functions, linear matrix inequalities (LMIs)-based H-infinity performance optimization and controller design are presented
for NCSs with limited communication channels. If there do not exist any constraints on the communication channels, the
proposed design methods are also applicable. The merit of the proposed methods lies in their less conservativeness, which is
achieved by avoiding the utilization of bounding inequalities for cross products of vectors. The simulation results illustrate
the merit and effectiveness of the proposed H-infinity controller design for NCSs with limited communication channels. |
