| Popis: | Aiming at the actuation system force fight problem resulted from active-active operational mode of fly-by-wire aircraft, and considering the technical maturity and reliability from safety aspect, the inertial integration algorithm and PI control law are established. After tradeoff study on these two methods, the PI control law is selected lastly.By physical model equivalent transformation, mechanical kinetics analysis, position closed-loop servo control modeling and AMEsim modeling and simulation analysis of the actuation system, the results show that using PI control can make the static force fight almost decrease to zero, make the dynamic force fight decrease to 1.288 9×106 Pa, 62.58% lower than requirement.It demonstrates the feasibility of the designed PI control law, and can be taken as the theoretic evidence of the forthcoming force fight equalization test on test rig. |
