Open loop load force estimation systems and methods

摘要

What is described is a system for determining a force applied to an outer disc of an aircraft brake by an actuator motor. The system includes a current sensor coupled to the actuator motor and configured to detect an amount of current applied to the actuator motor. The system also includes a controller coupled to the current sensor. The controller is configured to determine an estimate of the force applied to the outer disc based on the detected amount of current and predetermined input parameters.

1. A system for determining a current amount of force applied to a disc brake system of an aircraft, the system comprising:
an aircraft brake having a plurality of discs including an outer disc; an actuator configured to apply a force to the outer disc to compress the plurality of discs to reduce an angular velocity of wheels of the aircraft; a current sensor coupled to the actuator and configured to detect a detected amount of current applied to the actuator; and a controller coupled to the current sensor and configured to receive input parameters including a maximum force that can be applied by the actuator, a maximum current of the actuator that causes the actuator to apply the maximum force, and an efficiency fraction of the actuator that corresponds to an efficiency of the actuator and to determine an estimate of the current amount of force applied to the outer disc based on the detected amount of current and the input parameters.
