Which failure arises when a PID controller in a chemical reactor overheats due to thermal drift?

💡 Explanation

When a thermally drifting PID controller overheats, the control parameters (P, I, D) deviate from optimal, resulting in instability and therefore oscillating temperatures with positive feedback. Thus temperature oscillations happen, rather than flow cessation, runaway reaction, or averaging errors all requiring separate, additional system failures.
