Design and implementation of C-MEX S-functions in an Android-based networked control system laboratory

Abstract

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.

An output formation consensus control for leader–follower networked multi‐agent systems under communication constraints and switching topologies

“…As shown in the Figure 2, the 3-DOF Air-Bearing Spacecraft (ABS) simulator is an experimental equipment used to simulate the motion and control of spacecraft such as satellites in outer space on the ground, which has great engineering values [36]. These simulators can effectively verify the control tasks of various spacecraft or combined spacecrafts, such as, formation, flying-around, docking, capturing, etc., thanks to the advantages of their micro-gravity movement environment [37].…”
