Which effect occurs when a proportional valve undershoots rapidly in a hydraulic actuator system?

A)Reduced kinetic energy transfer
B)Increased positional settling time
C)Elimination of hydraulic lockup
D)Lower valve spool temperature

💡 Explanation

Undershooting can cause increased positional settling time because integral windup occurs; the PID controller's integral term accumulates error, therefore causing oscillation around setpoint rather than direct stabilization because other gains need time to compensate.
