Research on command synthesis technology of linkage cockpit steering for dual-pilot aircraft
Steering command synthesis is very important for modern fly-by-wire flight control system aircraft,espe-cially the linkage steering mode of dual-pilot brings great complexity to control command synthesis.Based on the role of the pilot and the fault mode of the steering,this paper analyzes the command synthesis concept of the steer-ing,designs the command synthesis logic algorithm,and studies the design consideration of the control command shaping.The simulation results show that this method successfully realizes the correct selection of the command un-der the conditions of the normal,sensor fault and one-sided mechanical stuck fault of the dual-pilot linkage steering,and solves the problem of high safety command synthesis of the complex steering of the fly-by-wire control system,which has good engineering application value.
