CAN-based message scheduling problem is illustrated in detail in the thesis, the merit and demerit of the typical dynamic (EDF) and static RM) scheduling algorithm and the influence on NCS performance are analyzed. A kind of MTS is put forward, through setting up a NCS3 (containing 3 control loops). With the TrueTime toolbox simulation, the improvement on NCS performance is confirmed, and the Network utilization is improved.

The Android-based networked control system laboratory (NCSLab) is a remote control laboratory that adopts an extensible architecture, mainly including Android mobile devices, MATLAB servers, controllers and test rigs. In order to conduct various simulations and experiments more effectively in NCSLab, the first key issue that needs to be solved is to enable users to design their own control algorithms or functional blocks on the Android client, rather than just using the basic block libraries provided by the system. So, this paper proposes and implements a scheme for Android-based compilation of C-MEX S-functions. With this new feature, users can design personalized algorithm according to their requirements in the form of S-functions, which can be called and executed after being compiled by MATLAB server. Finally, through the experiment validation of the three-degree-of-freedom air bearing spacecraft platform, it is proved that the method of Android-based C-MEX S-functions is reliable and efficient, and this scheme well enhances the functionality and mobility of Android-based NCSLab.
