🔍 Key Concepts

• Governor control characteristics for a prime mover (engine or turbine) • Meaning of hunting in speed control systems • Differences between stability, sensitivity, promptness, and dead band in governors

💭 Think About

• Think about what happens if the speed control system keeps over-correcting and oscillating around the set speed. Which term describes the governor’s ability to avoid that behavior? • Which option describes "how steady" the speed stays once it has reached the desired value, rather than how quickly or how finely it responds? • Consider which term refers to a range where no correction is made at all, and which term refers to too much or too little correction.

✅ Before You Answer

• Make sure you understand that hunting means repeated oscillation above and below the desired speed. • Identify which term is mainly about steadiness at the set speed, not about quickness of response or tiniest detectable change. • Eliminate the choice that describes a no-response zone, since that is different from maintaining speed without oscillation.
