← TechnologyWhich outcome results when gain is set too high in PID temperature control system?
A)Overshoot and sustained oscillations✓
B)Permanent offset from the setpoint
C)Slow response time and instability
D)Complete termination of system operation
💡 Explanation
When gain is too high in a PID controller, excessive correction occurs because the controller aggressively reacts to even small errors, leading to overshoot and oscillations around the setpoint. Overshoot and oscillations result, rather than offset, slow response or system termination which require different controller settings or component failures.
