| Abstract: | Multichannel force loading control system,which could economically and efficaciously simulate the aerodynamic loading of the aircraft,is a very important testing equipment in test-bed.According to the analysis on the cause of the extraneous force,the compensation method based on the structure-invariable principle is used to restrain the influence of the movement of the aircraft actuator,and increase the dynamic precision of the force loading system. |
