← TechnologyWhich uncontrolled motion results when cylinder pressure lags command signals controlling a hydraulic actuator?
A)Load oscillation begins immediately✓
B)Creep occurs at steady-state
C)Overpressure induces thermal runaway
D)Hysteresis generates static friction
💡 Explanation
Load oscillation begins because a pressure control mismatch can cause the actuator to overshoot its commanded position, triggering the hunting instability mechanism. Corrective action oscillates around steady-state, rather than initiating creep. Therefore, oscillations dominate, rather than other issues.
