Abstract
A system and methods for redundant current-sum feedback control of an actuator system is presented. An actuator comprises actuation coils configured to actuate the actuator, and an actuation coil current sensor senses a measured total coil current comprising a sum of coil currents of each of the actuation coils. Actuator coil controllers control the actuation coils based on a commanded total coil current and the measured total coil current.

A redundant current-sum feedback actuator system comprising:
- an actuator comprising a plurality of actuation coils configured to actuate the actuator;
- an actuation coil current sensor configured to sense a measured total coil current comprising a sum of coil currents of each of the actuation coils;
- and
- a plurality of actuator coil controllers configured to control the actuation coils based on a current-sum difference between a commanded total coil current and the measured total coil current.
A method for suppressing non-optimality in an actuator control system, the method comprising:
- sensing a measured total coil current comprising a sum of coil currents of each of a plurality of actuation coils of an actuator with an actuation coil current sensor;
- and
- controlling the actuation coils with a plurality of actuator coil controllers based on a current-sum difference between a commanded total coil current and the measured total coil current.
A redundant current-sum feedback actuator controller comprising:
- an inner feedback control loop configured to:
- receive a desired total coil current and a measured total coil current comprising a sum of coil currents of each of a plurality of actuation coils of an actuator;
- and
- control the actuation coils based on a current-sum difference between the desired total coil current and the measured total coil current.
