Which output characterizes a robot arm’s instability arising from sensor lag?

💡 Explanation

Oscillatory motion arises because sensor lag causes the control system to react to outdated position data, applying corrections repeatedly past the target, rather than smoothly reaching it. Over-correction results; therefore oscillations result rather than stable positioning.

• Which outcome arises when a multi-stage centrifugal pump experiences excessive clearance between its impeller and diffuser rings?
• Which outcome results when a gasoline direct injection (GDI) engine experiences fuel injector dribble at shutdown?
• Within a satellite transponder, which mechanism creates intermodulation signal distortion when multiple carriers are amplified simultaneously?
• Which risk increases when a control valve undergoes rapid closure in a long hydraulic pipeline?
• Which outcome occurs in a lean-burn engine when fuel injectors degrade unevenly?
• Which risk is amplified when concrete is poured too slowly around densely packed rebar?
