Which aspect is NOT typically part of loop tuning?

In loop tuning, the primary focus is on adjusting the performance of control loops to achieve optimal system response and stability. This process involves modifying parameters related to the control strategy, particularly the proportional, integral, and derivative (PID) settings, to meet performance specifications.

Increasing the power supply voltage, however, does not fall under the umbrella of loop tuning. This action typically pertains to power system adjustments rather than control system performance. The other aspects, such as adjusting PID settings, monitoring the system's output, and setting the control strategy, are directly related to ensuring the control loop functions effectively.

Each of these elements plays a vital role in tuning the loop, ensuring that the system achieves the desired setpoint and responds appropriately to disturbances. In contrast, power supply adjustments are more about ensuring that the system components are adequately powered rather than fine-tuning how those components interact within the control loop.
