What is the primary purpose of tuning a system in engineering?

The primary purpose of tuning a system in engineering is to ensure that it operates at its optimal performance levels. While many scenarios involve addressing vibrations, tuning broadly encompasses adjusting various parameters to reach desired performance outcomes.

Tuning is often associated with control systems and mechanical systems where resonance must be strategically managed to prevent excessive vibrations that could lead to system failure. By tuning the system, engineers can adjust the parameters such as damping, stiffness, and input/output characteristics, allowing the system to respond effectively to inputs and disturbances.

In the scope of the options provided, the focus on eliminating vibrations reflects a significant area where tuning is applied; however, tuning extends beyond just vibrations. It may also improve response times, stability, and overall effectiveness, making the system more efficient.
