Which control system instability arises when excessive sensor input lag?

💡 Explanation

Excessive sensor lag interacts with the PID controller causing potential instability namely self-oscillation, because feedback used for correction is delayed in response; therefore self-oscillation occurs due to accumulating phase shift, rather than immediate error correction.
