Abstract: Controller is provided for electromechanical actuator such as an electric brake actuator having a motor driven in response to motor drive signal generated by controller. Controller includes first current limiter and second current limiter. First current limiter limits current command to maximum current limit in response to detecting that current command at least one of exceeds maximum current limit setpoint or is less than minimum current limit setpoint. Second current limiter further limits current and to limited current command in response to detecting that current command exceeds topper current detection limit for specified time duration. Controller may further include intermediate current limiter between first and second current limiters for further limiting current command from first current limiter in response to detecting current command from first current limiter at least one of exceeds maximum power limit setpoint or is less than minimum power limit setpoint.
