For open control system which of the following statements is incorrect ?
Correct answer: B. Recalibration is not required for maintaining the required quality of the output
- A. Less expensive
- B. Recalibration is not required for maintaining the required quality of the output
- C. Construction is simple and maintenance easy
- D. Errors are caused by disturbances
Explanation
Open-loop systems cannot automatically correct changes in plant characteristics or operating conditions, so periodic recalibration may be needed to maintain output quality. Their simplicity and low cost are genuine advantages.
