1-20. (canceled)
A system, comprising:
- a submersible actuator, comprising:
- a first electric motor;
- a second electric motor;
- and
- a control circuit configured to control the first and second electric motors in a master-slave configuration to actuate a submersible flow control device.
2 more elements
A system, comprising:
- a submersible actuator, comprising:
- a first electric motor;
- and
- a control circuit configured to control the first electric motor to actuate a submersible flow control device, wherein the control circuit is configured to compare a value of a control signal with an average of a number of previous control signals.
1 more element
A system, comprising:
- a submersible actuator, comprising:
- a first electric motor;
- and
- a control circuit configured to control the first electric motor to actuate a submersible flow control device, wherein the control circuit is configured to calculate a maximum value for speed based on a total displacement time for the submersible flow control device.
