Closed 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 a detected 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 estimated current. The controller is also configured to receive the detected amount of current. The controller is also configured to determine an adjusted current based on the detected amount of current and the estimated current. The controller is also configured to determine an estimate of the force applied to the outer disc based on the adjusted current.

1. A system for determining a 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 measured amount of current applied to the actuator; and a controller coupled to the current sensor and configured to:
determine an estimated current applied to the actuator based on the measured amount of current detected by the current sensor that is applied to the actuator, determine an adjusted current based on the measured amount of current and the estimated current, and
determine an estimate of the force applied to the outer disc based on the adjusted current.
