  • Multiple electromechanical actuator control system
    Patent number: 10483880
    Abstract: A system for controlling multiple actuators that are attached to a structure for moving and positioning the structure include a magnetic flux sensor in a motor of each actuator. The magnetic flux sensor senses a magnetic flux in an associated motor and generates an electrical signal that corresponds to the magnetic flux in the associated motor. The system also includes a control unit that receives the electrical signal from the magnetic flux sensor of each actuator. The control unit is configured to generate a drive command signal to each actuator that balances a torque applied to the structure by each actuator in response to the magnetic flux sensed in the motor of each actuator.
