Abstract
A controller for an electromechanical brake actuator (EBA) is provided. EBA has a motor driven in response to a motor drive signal generated by controller. Controller includes a velocity limiter and a current limiter. Velocity limiter limits a velocity command in response to a measured braking force signal output. Limited velocity command has a positive velocity limit boundary defined between a positive maximum velocity limit setpoint and a positive minimum velocity limit setpoint and a negative velocity limit boundary defined between a negative maximum velocity limit setpoint and a negative minimum velocity limit setpoint. Current limiter limits a current command in response to the measured braking force signal output. Limited current command has a positive current limit boundary defined between a positive maximum current limit setpoint and a positive minimum current limit setpoint and a negative current boundary defined between a negative maximum current limit setpoint and a negative minimum current limit setpoint.
