← TechnologyWhich outcome results when instability undermines closed-loop hydraulic control?
A)Aggressive actuator oscillations occur✓
B)Fluid bulk modulus increases notably
C)Pump experiences mechanical overspeed
D)Reservoir temperature decreases suddenly
💡 Explanation
Actuator oscillations may develop in precision systems, because negative feedback attempting overshoot correction causes increased control signal excursions using proportional-integral-derivative (PID) gain, resulting therefore in induced oscillations, rather than damped movements or stable equilibrium.
