In a stable control system backlash can cause which of the following?
A. Underdamping
B. Overdamping
C. Poor stability at reduced values of open loop gain
D. Low-level oscillations
Answer:D
In a stable control system backlash can cause which of the following?
A. Underdamping B. Overdamping C. Poor stability at reduced values of open loop gain D. Low-level oscillations
Explanation: In stable control systems backlash is the form of the error which may cause low level of the oscillations and hence can be useful sometimes as it increases the damping.
