Design of Measurement and Control System of Suspension Support Device Based on LabView and FPGA

To ensure flight safety of newly developed aircraft model, it is necessary to conduct wind tunnel stability tests of a scaled-down aircraft model under support of a multi-degree-of-freedom suspension support device in a wind tunnel. In this paper, measurement and control system of the suspension support device is designed to adjust aircraft model's attitude and collect information from various sensors of the support device. The measurement and control system was designed based on LabVIEW and FPGA; FPGA control board is responsible for servo motor control, and control and measurement software system was built by using LabVIEW. This system is responsible for signal transmission and reception, data processing, and storage. Following experimental verification, it has been demonstrated that the measurement and control system designed in this paper can meet requirements of parallel processing of multiple data types, large amounts of information, and aircraft model attitude control during the test.
