This is the Birla Institute of Technology and Science, Pilani-First Semester Control Systems (AAOC C321) Exam Previous Years Question Paper:

Consider the system given in Fig Q3. When the system is subjected to a unit step
input the output has peak overshoot of 16.3% but ultimately attains the final
value of 1 unit. The response to a ramp input has a steady state error of 0.0625
unit.
(a) Find the values of K, a & b (all three are  0),
(b) For the system with above calculated values, add a suitable error controller
(Gain K1) to get steady state error as zero and determine the range of K1 for
system to be stable,
