Abstract
An aircraft user interface haptic feedback system includes a user interface, a position sensor, a cogless motor, and a control circuit. The user interface is movable to a position. The position sensor senses the position of the user interface and supplies a user interface position signal. The cogless motor is coupled to the user interface, and receives motor drive signals. The cogless motor, in response to the motor drive signals, supplies feedback force to the user interface. The control circuit receives at least the user interface position signal and a signal representative of the motor current and is operable, in response to at least these signals, to control the motor current supplied to the cogless motor using a non-trapezoidal motor commutation scheme.
