Title: FORCE AND POSITION CONTROL OF ELECTRICAL BRAKE ACTUATORS
Abstract:
A system and associated method for achieving both force and position control of motor-driven electrical brake actuators for a brake disc stack that has, and seeks to maintain, a characteristic built-in clearance among the discs. The system employs both force feedback and motor turns position feedback associated with the actuator during a braking operation in order to obtain a motor turns position that achieves the characteristic built-in clearance following braking action or the like.
