Q

Which of the following control modes is generally not used by itself?

🔍 Key Concepts

• Control modes in automatic controllers: proportional (P), integral (I), derivative (D) and their typical uses • How each mode behaves if it is used alone to correct an error signal over time • Stability and practicality of using a single control mode in a real shipboard system

💭 Think About

• Think about which mode mainly reacts to how fast the error is changing rather than the size of the error itself • Ask yourself: which mode, if used alone, could make the system too sensitive to noise, sudden changes, or small disturbances? • Consider which modes are commonly combined together in PID control because they compensate for each other’s weaknesses

✅ Before You Answer

• Identify which mode depends on the rate of change of the error, not the error itself • Consider which mode, by itself, would not drive the error steadily to zero in a practical control loop • Recall which mode is usually added to other modes to improve response, rather than being used as the only mode
