← TechnologyWhich risk dramatically increases when quadrature encoder pulses are missed in a closed-loop robotic arm?
A)Integrator windup becomes dominant.✓
B)Damping factor abruptly increases.
C)Processor load is unaffected.
D)Motor torque demand decreases.
💡 Explanation
Missed encoder pulses introduce position error which the controller will aggressively attempt to correct; the integral term increases, possibly leading to integrator windup, because the `error accumulation` mechanism leads to command saturation; therefore windup ensues, rather than correct feedback or decreased demand.
