英文摘要:

      Aiming at the high frequency control requirements for the active control technology of aeroengines， the design method of an ultra-high speed rapid control prototype based on compact RIO/FPGA was proposed. The hardware platform of the rapid control prototype was built. The control algorithm and the I/O interface driver programs were designed by using LabVIEW. A second order system model with the bandwidth of 311 Hz which was developed by an analog circuit was taken as a quick response control object， and the ultra-high speed closed-loop control of 20 microseconds control step was carried out in the hardware in the loop(HIL) test， which can verify the rapid control prototype to be effective. The results show that the ultra-high speed rapid control prototype based on compact RIO/FPGA is a good way to meet the high-frequency control demand of aeroengine active control technology.
