Question
A unity negative feedback system has an open-loop transfer function . The gain for the system to have a damping ratio of 0.25 is ________.
Correct answer
400 to 400
Solution
The characteristic equation of the unity negative feedback system is given by .Comparing this with the standard second-order characteristic equation :
1.
2.
Given the damping ratio :Now, find the gain :Continue learning with Success Tracker
