In order to meet the basic application research of aerodynamics, build the 0.6 m wind tunnel into a research test platform, a measurement and control system is researched and developed. Constructed the four degree freedom motion control system by using SIMATIC T-CPU315 as the control core and completed the whole test process through the communication between Ethernet and other subsystems. Introduced the project implementation and solved technology problems in detail. Explained debug and application situation and gave main calculation. The test results show that the new system performance is good, high control precision and the force measurement test results of the standard model are well which satisfy to the demand of national military standard.
