“…The functions of online algorithm design and execution have been accomplished, such as real-time monitoring configuration interface construction [28], three-dimensional (3D) interaction [29][30][31], virtual wiring practice based on HyperText Markup Language 5 (HTML5). As shown in Figure 2, NCSLab can be divided into a fourlayer network structure [32,33]. They are the clients' side, central web servers, regional experimental server, and test rigs.…”

“…Compared with these simple control systems [33], large and complex control systems have the following characteristics 1)Complex systems are often the collection of multiple simple systems. Their complex internal structure and strong coupling lead to greater difficulties in the modeling process. 2)Many complex systems are nonlinear and MIMO system, where there are many signals and parameters need to be observed and adjusted. 3)Some complex system may lead to more control details to be presented, especially in the system 3D model. 4)In the application industry of many complex systems, industry norms and customary expressions are faced with professional practice.…”

Online experimental systems that include remote and virtual experiments based on the Internet has become a new form of experiment in engineering education. This paper proposes a virtual experiment for the complex process control system. It is based on the networked control system laboratory (NCSLab), which provides a reliable framework for virtual thermal experiment. Taking the combustion system of 1000 MW ultra-supercritical coal-fired once-through boiler-turbine units as an example, the framework and the implementation process of the online system are given in this paper. A new presentation form for complex processes control experiment is provided, which could be a solution for simulating physical experimental equipment in virtual environments. The potential danger in practical experiments could be avoided. Additionally, the real-time operation for complex control systems could be presented in a 3D scene. Meanwhile, the flexibility and efficiency could be increased in engineering experimental education. Moreover, using the experiment evaluation method, the references and feedback for teaching and assessment are provided in this paper.

“…For example, VNLab (Prieto-Blazquez et al, 2008), MIT iLab (Harward et al, 2008), eComLab (Melkonyan et al, 2014), and WebLab (Gustafsson et al, 2015;Rodriguez-Gil et al, 2014), all of them have been validated in practice. Especially, the online 3-D interactive experimental system proposed by Lei et al (2018Lei et al ( , 2020 has high engineering practical significance. However, since the virtual laboratory consists of virtual laboratory platform, virtual equipment library and open laboratory management system, its experimental data are obtained according to the parameters of the simulation model, rather than the real system environment.…”

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.

This paper presents the design and implementation of the control algorithms design module based on a remote laboratory named NCSLab, which allows students, teachers, and researchers to do practical experiments with various control systems remotely via the Internet whenever and wherever they want.To meet the demand of students with different levels and provide more extensibility, a flexible control algorithm designing system is deployed using a frontend and backend separation framework. JointJS is selected to construct the graphic user interface and an algorithm server is developed to deal with the algorithms tasks. In this way, the users are able to customize control systems online with a visualized interactive interface. A control algorithm could be formed easily without programming, so the users could concentrate on the control algorithm itself. For advanced users, customized C-MEX S-Functions are available for extra sophisticated control systems. The designed control algorithms are converted into executable codes at the back-end by the servers. They could be implemented into the remote test rigs and then the corresponding results would be sent back in real-time. The overall implementation is based on the web, so only common browsers and Internet access are needed. By logging into the laboratory through the web, the users could start practical experiments quickly after acquiring the control right of the desired test rig. And the whole process, including designing, simulating, and generating codes, is integrated into the interface of the proposed system module, which is easy to use and could bring great convenience to the users.
