The presence of nonlinearities in a control system tends to introduce
Which one of the following is not a property of the Liapunov function?
The number of sign changes in the Routh’s array indicates the number of roots lying in the
Assertion (A): A system is said to be stable if the impulse response approaches zero for sufficiently large time.
Reason (R): If the impulse response approaches infinity for sufficiently large time, the system is said to be unstable
The open loop transfer function of a unity feedback system is
What is the range of value of K so that the closed loop system is absolutely stable?
Assertion (A): If the system is stable we can determine the relative stability by the settling time of the system.
Reason (R): If the settling time is less than that of the other system then the system is said to be relatively more stable.
If the unit step response of a system is given by c(t) = 1.5 + e^{t} + 0.5e^{2f}, then the system will be
The characteristic equation of a servo system is given by
a_{0}s4 + a_{1}s^{3} + a_{2}s^{2} + a_{3}s + a_{4} = 0
Now, consider the following conditions required to be satisfied by the coefficient of the above characteristic equation for the system to be stable:
1. a_{1} > 0 and a_{4} > 0
2. a_{1} < 0 and a_{4} > 0
3. a_{1}a_{2}< a_{0}a_{3}
4. a_{1}a_{2} > a_{0}a_{3 }

Which of the above conditions holds true for the given system to be stable?
The open loop transfer function of a unity feedback control system is given by
The oscillating frequency of the given system is
The characteristic equation of a system is given by s^{3} + s + 2  0.
What are the number of roots in the right half splane and on the jωaxis respectively?
