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.

Electrical actuator systems and methods for limiting force in the event of a wiring harness failure

An image gathering system includes an intelligence, surveillance and reconnaissance (ISR) device, an isolation system with a damper, and a controller operatively associated with the damper. The damper has a vehicle coupling and a payload coupling, and the payload coupling is connected to the ISR system. The controller is operatively associated with the damper to change the damping coefficient of the damper based on an expected vibration signature of a vehicle coupled to the isolation system through the vehicle coupling of the damper.

Isolation systems for image data gathering devices

Systems and methods of controlling a brake system are provided. The system may include the step of detecting, by a controller, a failure of a first load cell of a first electromechanical brake actuator (EBA). The method may further comprise estimating, by the controller, a force of the first EBA using a force output from a second load cell, and commanding, by the controller, the first EBA in response to the estimated force of the first EBA.
