  • Patent number: 10421536
    Abstract: A control method for controlling an electrical taxiing system adapted to moving an aircraft while it is taxiing, the method comprising the steps of: generating a ground speed setpoint for the aircraft; transforming the ground speed setpoint into an optimized speed setpoint presenting a curve as a function of time that has a predefined function comprising a plurality of linear portions, each having a slope that is a function of the ground speed setpoint; implementing a regulator loop having the optimized speed setpoint as its setpoint; and generating a command for the electrical taxiing system from an output of the regulator loop.

  • Patent number: 10365632
    Abstract: A method of controlling an aircraft electrical taxiing system, the method comprising the steps of: defining a target value (Ld_nmax) for an electrical parameter; generating a nominal force command (Cmd_nom) for the electrical taxiing system; in parallel with generating the nominal force command (Cmd_nom), using a processing system (2) to produce a maximum command force (Force_max) for the electrical taxiing system so that a real value of the electrical parameter reaches the target value (Ld_nmax), the processing system (2) comprising a regulator loop (4); and generating an optimized force command (Cmd_opt) for the electrical taxiing system equal to the smaller of the nominal force command and the maximum command force.

  • Patent number: 10268196
    Abstract: A method for controlling an aircraft taxiing system, comprising the steps of: generating a nominal load command (Comm_nom); generating an acceleration setpoint (Cons_a); implementing, in parallel with the generation of the nominal load command, a processing chain (7) comprising a regulation loop (Br), the regulation loop (Br) having for its setpoint the acceleration setpoint (Cons_a) and for its command an acceleration command (Comm_a), the acceleration command being converted into an acceleration load (Eff_a), a maximum load threshold being equal to the maximum of the acceleration load (Eff_a) and a minimum load threshold (Seuil_min); and generating an optimized load command (Comm_opt) equal to the minimum of the nominal load command and the maximum load threshold.
