DC motor control in a 3D real-time virtual laboratory environment

Virtual laboratory has been introduced to remote learning as well as experimental classes of universities in the last few decades. In a virtual laboratory, automatic control theory can be well verified by conducting experiments on models such as water tanks, inverted pendulums and DC motor. In this paper, a DC motor control system which can experiment the position control in real time based on Networked Control System Laboratory (NCSLab) is present. After a description of the process of 3D modelling and rendering in Flash 3D engine as well as control algorithms which are generated using Real Time Workshop, the experiment of position control is conducted and the control results are shown in a picture snapped from the real-time monitoring. The old NCSLab 3D system only allows users to design the algorithms and then simulate them. However, when it comes to the wiring, nothing can be done by the users. This paper proposed a method which allows the users to do the wiring in the 3D real-time virtual laboratory. It could make users feel more sense of reality and immersion to conduct the experiments.
