Abstract: Wind tunnel test of propeller aerocraft model, the need for realtime control of the servo motor with high power density, cycle cooling. In this article, through the analysis of the wind power system operating environment, made specific design for its special operation environment, successfully solved the system running reliability and stability. The design of the actuation driving control system, can realize the scene of the four servo motor and remote monitoring, and record the running data. Actual operation results show that the system has easy operation, perfect function, high control precision, stable and reliable operation, etc. The system has high engineering application value.
