The forward path transfer function of a ufb system is If a unit ramp is applied, the minimum possiblesteady-state error is

Solution:

Using Routh-Hurwitz Criterion, system is stable for 0 < K < 2000 QUESTION: 9

The forward-path transfer function of a ufb system is The system has r(t) = t3 applied to its input. Thesteady state error is

Solution:    QUESTION: 10

Consider a unity feedback system with forward transfer function given by The steady-state error in the output of the system for a unit-step input is _________ (up to 2 decimal places).

Solution: QUESTION: 11

A system has position error constant Kp  = 3. The steady state error for input of 8tu(t) is

Solution:

System is zero type QUESTION: 12

The forward path transfer function of a unity feedback system is For input of 60u(t) steady state error is

Solution:  QUESTION: 13

For ufb system shown in fig. the transfer function is If input is 30t2 , then steady state error is

Solution:  QUESTION: 14

The forward-path transfer function of a ufb control system is The steady state errors for the test input 37tu(t) is

Solution:  QUESTION: 15

In the system shown in fig. r(t) =  1 + 2t , t > 0. The steady state error e(t) is equal to Solution:

The system is type 2. Thus to step and ramp input error will be zero.   QUESTION: 16

A ufb control system has a forward path transfer function If the system is subjected to an input r(t) = 1 + t + 1/2 t2 , t > 0the steady state error of the system will be

Solution:

Explanation : R(s) = (1/s)+(1/s2) + (1/s3)

E(s) = R(s) / {1 + G(s)} = 1/10s

ess = lim sE(s) = 0.1
