1. A method for controlling a drive motor system mounted within an aircraft nose wheel to drive the aircraft independently on the ground without the use of the aircraft main engines in accordance with one or more stationary, forward or reverse aircraft operational states, said method comprises:
a. housing within at least one aircraft nose wheel an electrically powered drive motor system comprising a stator-rotor combination adapted to generate a requested nose wheel torque or speed in response to one or more selected stationary, forward or reverse aircraft operational states to drive said at least one nose wheel, and electronically connecting drive electronics to said stator-rotor combination; b. operationally connecting a pilot interface to said electrically powered drive motor system comprising a plurality of input devices and a plurality of notification devices adapted to overlap with said plurality of input devices, each of said input devices being adapted to actuate a power command and to move the aircraft at a drive motor torque in a selected direction as required by the one or more selected stationary, forward or reverse aircraft operational states; c. providing a plurality of sensors in connection with said plurality of input devices, said at least one nose wheel, and said electrically powered drive motor adapted to provide information relating to each of said one or more selected stationary, forward or reverse aircraft operational state; d. electronically connecting hardware drivers to said plurality of input devices and said plurality of sensors adapted to calibrate power commands and sensor information to produce input device variables relating to each said one or more selected stationary, forward or reverse aircraft operational state; e. electronically connecting control loop means to said hardware drivers, said plurality of sensors, and said plurality of input devices, wherein said control loop means comprises state change law means for defining state change laws for said input device variables, system state means for applying the state change laws to determine an aircraft nose wheel stationary, forward or reverse operational state, first parameter filter limit law (PFLL) means for filtering selected ones of said input device variables according to a first set of out-of-bounds conditions, first calculation means to determine a torque or speed request to apply to the drive motor in accordance with filtered selected input device variables, second parameter filter limit law (PFLL) means for filtering a requested torque or speed, second calculation means to determine a motor drive frequency and motor voltage to produce the filtered requested torque or speed motor command generator means for producing lower level commands to drive the drive motor based on a determined motor drive frequency and motor voltage corresponding to the filtered requested torque or speed, and motor commander means for formatting said lower level commands for said drive motor; and f. providing drive electronics connecting said plurality of input devices, said plurality of notification devices, said plurality of sensors, said hardware drivers, said control loop means, and said drive motor adapted to supply electric power to the stator-rotor combination, and supplying electric power to said drive motor in accordance with said lower level commands to move said aircraft nose wheel at said requested torque or speed in accordance with a pilot-requested selected stationary, forward or reverse aircraft operational state. |
