Abstract

A method for controlling an electrical actuator is disclosed. The method may include driving an electrical actuator at a power level during each of a plurality of actuation attempts and determining whether the electrical actuator actuated during each of the plurality of actuation attempts. The method may also include counting a number of failed actuation attempts, counting a number of successful actuation attempts. In addition, the method may include adjusting the power level based on at least one of the number of failed actuation attempts and the number of successful actuation attempts, and driving the electrical actuator at an adjusted power level.

Claims

1. A method of controlling an electrical actuator, comprising:

driving an electrical actuator at a power level during each of a plurality of actuation attempts;

determining whether the electrical actuator actuated during each of the plurality of actuation attempts;

counting a number of failed actuation attempts;

counting a number of successful actuation attempts;

adjusting the power level based on at least one of the number of failed actuation attempts and the number of successful actuation attempts; and

driving the electrical actuator at an adjusted power level.

2. The method of claim 1, further comprising increasing the power level based on the number of failed actuation attempts reaching a failure-count threshold.

3. The method of claim 1, further comprising decreasing the power level based on the number of successful actuation attempts reaching a success-count threshold.

4. The method of claim 1, further comprising increasing the power level based on the number of successful actuation attempts being less than a threshold number of successful actuation attempts for maintaining the power level.

5. The method of claim 1, further comprising calibrating the power level to an optimized power level for actuating the electrical actuator.

6. The method of claim 5, further comprising implementing a calibration settling speed by setting at least one of a success-count threshold for decreasing the power level, and a failure-count threshold for increasing the power level.

7. The method of claim 1, further comprising:

sensing an environmental condition associated with the electrical actuator; and

adjusting the power level by one of an increment power level and a decrement power level, the increment power level and the decrement power level based on the sensed environmental condition.

8. A system, comprising:

an electrical actuator; and

a controller electrically coupled to the electrical actuator and configured to;

drive the electrical actuator at a power level during each of a plurality of actuation attempts;

determine whether the electrical actuator actuated during each of the plurality of actuation attempts;

count a number of failed actuation attempts;

count a number of successful actuation attempts;

adjust the power level based on at least one of the number of failed actuation attempts and the number of successful actuation attempts; and

sense an environmental condition associated with the electrical actuator; and

adjust the power level by one of an increment power level and a decrement power level, the increment power level and the decrement power level based on the sensed environmental condition.

15. A non-transitory machine-readable medium comprising instructions stored therein, the instructions executable a processor to facilitate performing a method for estimating the efficiency of a drilling tool, the method comprising:

driving an electrical actuator at a power level during each of a plurality of actuation attempts;

determining whether the electrical actuator actuated during each of the plurality of actuation attempts;

counting a number of failed actuation attempts;
