Abstract
A method of controlling a drive system of an aircraft. The drive system comprised a drive motor arranged to drive at least one wheel of an aircraft landing gear. A power signal indicative of a power level for the drive motor and a speed signal indicative of a rotation speed of the drive motor are received. A torque level for the drive motor is determined using the power signal and the speed signal. The drive motor is then driven such that the torque generated by the drive motor is at the determined torque level.
Claims18
A method of controlling a drive system of an aircraft, wherein the drive system comprises a drive motor arranged to drive at least one wheel of the aircraft landing gear, the method comprising the steps of:
- receiving a power signal indicative of a desired power level for the drive motor such that the drive motor avoids jerking the aircraft:
- receiving a speed signal indicative of a rotation speed of the drive motor;
- determining a torque level for the drive motor using the desired power signal and the speed signal;
- and,
- driving the drive motor such that the torque generated by the drive motor is at the determined torque level.
A method of controlling a drive system of an aircraft, wherein the drive system comprises a drive motor arranged to drive at least one wheel of the aircraft landing gear, the method comprising the steps of:
- receiving a power signal indicative of a power level for the drive motor;
- receiving a speed signal indicative of a rotation speed of the drive motor;
- determining a torque level for the drive motor using the power signal and the speed signal;
- driving the drive motor such that the torque generated by the drive motor is at the determined torque level, wherein the torque level is increased over time by at most a predefined maximum torque rate to provide smooth movement of the aircraft when there are large changes in the power level indicated for the drive motor.
A control system for controlling an aircraft wheel drive system, wherein the drive system comprises a drive motor arranged to drive at least one wheel of the aircraft landing gear, and wherein the control system is arranged to:
- receive a power signal indicative of a desired power level for the drive motor such that the drive motor avoids jerking the aircraft;
- receive a speed signal indicative of a rotation speed of the drive motor;
- determine a torque level for the drive motor using the desired power signal and the speed signal;
- and,
- drive the drive motor such that the torque generated by the drive motor is at the determined torque level.
An aircraft comprising:
- an aircraft wheel drive system;
- a control system for controlling the aircraft wheel drive system;
- wherein the drive system comprises a drive motor arranged to drive at least one wheel of the aircraft landing gear, and wherein the control system is arranged to:
- receive a power signal indicative of a desired power level for the drive motor such that the drive motor avoids jerking the aircraft;
- receive a speed signal indicative of a rotation speed of the drive motor;
- determine a torque level for the drive motor using the desired power signal and the speed signal;
- and,
- drive the drive motor such that the torque generated by the drive motor is at the determined torque level.
