Which risk increases when a PID controller's derivative gain amplifies high-frequency noise in robotic arm?

💡 Explanation

When high derivative gain amplifies noise, excessive and rapid corrections are commanded because the controller misinterprets noise as legitimate error, leading to frequent reversals and high stress on the actuators. Therefore actuator wear results, rather than processor load, sensor saturation or link vibration, which depend on other system parameters.
