Calibration

Prototype actuators verified the QCW control method. Test proved that

• Slight changes in electrical input cause slight changes in mechanical output.
  
  
• Slight changes in load cause slight changes in dynamics.

This sensitivity enabled fine adjustments to obtain desired mechanical output. Given appropriate electronics, an actuator can then

• Detect its environment.
  
  
• Auto-calibrate while operating.
  
  
• Follow a changing load.

Self-diagnostics, fault detection, and self-calibration contribute to on-condition maintenance only instead of at fixed intervals.

Repeatability

Repeatability obtains the same output for the same input.
