In a stable control system backlash can cause which of the following ?
Correct answer: D. Low-level oscillations
- A. Underdamping
- B. Overdamping
- C. Poor stability at reduced values of open loop gain
- D. Low-level oscillations
Explanation
Backlash introduces a dead zone and can produce small sustained oscillations or limit cycles even when the linear control system is stable. It does not directly imply overdamping.
