doi:10.3901/JME.260243

Abstract

Abstract: To achieve visual monitoring and virtual debugging of reflector antennas, a high-fidelity digital twin system construction method is proposed based on the multi-domain unified modeling of the mechanical, electrical and control systems, and model parameter identification. First, the electrical model, machine model and control model of the azimuth and pitch joints are respectively constructed, and then coupled to build the multi-domain unified model according to information transmission and energy conversion laws. Then, the motion control system, data acquisition system and the Unity virtual monitoring system of the antenna physical entity are established to monitor operational status of the antenna physical entity in real-time, and collect the motion data and send to the upper computer in real-time. The dynamic parameters of the antenna's mechanical system are identified based on the motion data, and the parameters of the control and motor models are also updated, so that the real-time motion status of the physical antenna is accurately mapped by the multi-domain unified digital twin model. Finally, the motion performance of reflector antenna is virtually debugged based on the multi-domain unified digital twin model on a 0.9

Key words: reflector antennas, digital twin system, electromechanical coupling dynamic models, parameter identification, status monitoring, virtual debugging
