Which outcome occurs when sensor drift biases a closed-loop PID controller maintaining jet engine turbine inlet temperature (TIT)?

💡 Explanation

Combustion instability increases because integral windup drives the actuator to compensate for the sensor error due to the drifting measured TIT signal, which causes over-fueling therefore leading turbulence. Rather than fuel savings or tighter temperature control, surging is triggered.
