← TechnologyWhich risk increases when a robotic arm joint encoder experiences significant signal jitter?
A)Reduced control loop stability✓
B)Increased motor winding temperature
C)Sudden loss of power output
D)Unexpected vibrational resonance onset
💡 Explanation
Excessive jitter compromises the signal integrity relied on for position feedback to the PID control loop; this degrades performance because it introduces lag; therefore, proper system tuning is disrupted, rather than resulting in thermal overload or mechanical resonance.
