Abstract:
In this paper, the tracking performance of multiple input multiple output (MIMO) networked control systems (NCSs) with multiple communication constraints is studied. The effects of network induced factors (packet loss and network delay) and basic communication constraints (bandwidth, encoding-decoding and different noise) are considered. By inner-outer factorization and Youla parameterization, the mathematical expressions of the performance of the one-degree of freedom (1DOF) controller and two-degree of freedom (2DOF) controller are obtained, respectively. It shows that internal characteristics and network constraints have different effects on the tracking performance of the plant, and the performance of the 2DOF controller is better than that of the 1DOF controller. Finally, several simulation examples are provided to verify the influence of each constraint.

Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
