Design of Aircraft Direct Lift Control System Based on EMD and Closed-Loop Testing
The uneven direct lift of aircraft could cause the issue of flight yawing,in order to effectively control the aircraft's flight capabilities,a direct lift control system based on empirical mode decomposition(EMD)and closed-loop testing was designed.In the FSEU architecture,the ARINC429 bus closed-loop mechanism was set up.The servo control module and real-time onboard termi-nal were integrated to build the application mode of the aircraft's direct lift control system.The centroid dynamics equation was solved through defining the conditions for the hidden EMD information.Based on aerodynamic principles,the specific value of heading devia-tion was calculated to achieve the EMD-based lift control.Based on memory network crosslinking environment,the model organiza-tion was configured to improve the closed-loop testing functionality.Experimental results show that the designed system can improve the uneven lift and control the aircraft's yaw angle within the range of 0°~20°,effectively controlling aircraft's flight capabilities.
