← TechnologyWhich control instability results when a robotic arm's accelerometer exceeds its rated bandwidth during rapid movements?
A)Velocity saturation in the joints
B)Aliasing within the feedback loop✓
C)Increased encoder signal jitter
D)Thermal runaway occurrences
💡 Explanation
Aliasing occurs because the accelerometer samples motion at a rate slower than Nyquist frequency, resulting in frequency distortion and incorrect feedback; therefore control systems become unstable, rather than experiencing joint saturation under normal bandwidth.
