← TechnologyWhich outcome occurs when dithering is disabled on an electro-hydraulic servo valve?
A)Increased hysteresis loop size✓
B)Reduced valve spool friction
C)Improved steady-state tracking
D)Decreased system thermal load
💡 Explanation
Increased hysteresis results from disabling dithering, because dithering normally introduces a high-frequency, low-amplitude oscillation that prevents the valve spool from sticking. Therefore, the valve accuracy diminishes at command reversals, rather than allowing smooth, precise control.
