Multiple electromechanical actuator control system

A system for controlling multiple actuators that are attached to a structure for moving and positioning the structure, the system comprising:

• a magnetic flux sensor in a motor of each actuator, the magnetic flux sensor sensing a magnetic flux in an associated motor and generating an electrical signal that corresponds to the magnetic flux in the associated motor;
• and
• a control unit that receives the electrical signal from the magnetic flux sensor of each actuator, the control unit comprising:
• a threshold window detector configured to perform a function comprising detecting a magnetic flux density of a particular actuator being outside preset performance limits based on the electrical signal corresponding to the magnetic flux in the associated motor of the particular actuator;
• and
• a flux selector configured to perform a function comprising deactivating the particular actuator in response to the magnetic flux density of the particular actuator being greater than an upper preset limit or lower than a lower preset limit.

A method for controlling multiple actuators that are attached to a structure for moving and positioning the structure, the method comprising:

• sensing a magnetic flux using a flux sensor winding in a motor of each actuator, the flux sensor winding in each motor generating an electrical signal that corresponds to the magnetic flux in an associated motor;
• generating a plurality of signals, by a control unit, each signal representing a torque provided by the motor of each actuator to the structure based on a magnetic flux level in the motor of each actuator;
• comparing the signals by the control unit;
• and
• generating, by the control unit, a drive command signal to the motor of each actuator of the multiple actuators that balances the torque applied to the structure by each actuator in response to the magnetic flux sensed in the motor of each actuator.
