← TechnologyWhich risk increases when a drone's altitude hold system relies excessively on integral windup?
A)Reduced actuator control precision
B)Increased sensor data bandwidth use
C)Oscillatory vertical instability develops✓
D)Motor speed saturation is mitigated
💡 Explanation
Oscillatory instability increases because integral windup accumulates excessive error correction, leading to overshooting altitude objectives. Therefore, the drone oscillates rather than settling smoothly, due wind up rather than exclusively proportional or derivative controller action.
