Which outcome occurs when excessive dither in a servo valve controlling a hydraulic actuator generates frequency close to the natural resonance?

💡 Explanation

Reduced positional accuracy results because the dither excites the hydraulic actuator's natural frequency creating oscillations around the set point. This is due to the **Bode plot** exhibiting gain peaking. Therefore actuator positional accuracy is reduced, rather than losses minimized or increased fluid bulk modulus.
