Teaching System Identification by Remote Access to a Networked Control System Laboratory

Remote experiment courses can expand the boundaries of the classroom, allowing students to conduct experiments anytime and anywhere. This paper takes the system identification experimentation as an example to introduce how to use the remote laboratory to carry out online experiments for system identification. The physical equipment is deployed into the Networked Control System Laboratory (NCSLab) and is used to conduct remote experiments, and the corresponding input/output signal data are collected for parameter identification. The experiment course discussed in this paper combines system identification models, classical identification methods, least squares method, offline identification, online identification, and other theories to provide a thorough experimental design and experimental processes. To validate the effectiveness, the proposed method has been applied to an undergraduate system identification course at Wuhan University. The results show that the remote experiment course has positive application effects and is of great significance to the reform of the existing experimental teaching system.
