Abstract
A brake actuator comprising a DC motor, a computer configured for: measuring, over time, a current drawn by the motor and a voltage between the terminals of the motor; implementing a Kalman filter in order to compute, from the measured current and voltage, a filtered current drawn by the motor and a filtered rotational speed of a shaft of the motor; computing, from the value of the filtered current and the value of the filtered rotational speed, a clamping force that is produced by the actuator; controlling the motor such that it stops when the computed value of the clamping force reaches a predetermined setpoint value.
