Which failure occurs when piloting a large hydraulic actuator system experiences asymmetric valve spool sticking?

💡 Explanation

When spool sticking of the control valves is asymmetric, the hydraulic actuator system experiences uneven responsiveness because different actuators move at unequal speeds, inducing forces leading to feedback oscillation. Therefore system oscillation results, rather than load reversal, pressure amplification, or thermal runaway, which require different circumstances.
