Design of Control and Data Observation System of the Test Bench for the Electric Propulsion System in the Solar Aircraft

In order to control and test the electric propulsion system of the solar aircraft efficiently and conveniently, which includes a Brushless Direct Current (BLDC) drive machine and a load machine, this paper designed a test bench control and data observation system. This system is not only to control the operation status of the BLDC drive machine, but also to send instructions to the load machine. And through CAN bus and the power meter LMG670, the information, such as switch, current, voltage and rotational speed, is tested, transmitted and displayed with Lab View,as an overall virtual instrument platform for the system through data transmission.
