Which actuator response occurs when the hydraulic servo-valve's dither amplitude decreases to zero?

💡 Explanation

Decreased dither in the hydraulic servo-valve amplifies any surface imperfections and stick-slip friction. Stiction is lessened by small vibrations of the dither signal; therefore, the null non-linearity increases drastically rather than decreasing, optimizing bandwidth, or altering velocity.
