Which effect arises when a proportional valve causes rapid cycling in a hydraulic actuator controlling robotic arm position?

💡 Explanation

When a proportional valve causes rapid cycling, pressure fluctuations initiate resonant system behaviour, creating vibration due to rapid accelerations and deccelerations that lead to enhanced frictional losses in robotic joints. Therefore, vibratory wear on the joints leads to increased backlash, rather than stall torque increase, pressure surges, or thermal reductions, that could cause issues in other actuator implementations.
