The open-loop transfer function of a unity feedback system is K/(s^2 (s+5))The system is unstable for

Correct Answer: All of the mentioned
The open loop transfer function of a unity feedback system is used to calculate the conditional stability by using the Routh Hurwitz criteria or the Root locus technique.

Consider the following statements with respect to the feedback of the control systems. i. Feedback can improve stability or be harmful to stability if it is not properly applied. ii. Feedback can always improve stability iii. In many situations the feedback can reduce the effect of noise and disturbance on system performance. iv. In general the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located.

Consider the following statements: 1. The effect of feedback is to reduce the system error 2. Feedback increases the gain of the system in one frequency range but decreases in another 3. Feedback can cause a system that is originally stable to become unstable Which of these statements are correct.

The open loop transfer functions with unity feedback are given below for different systems. Among these systems the unstable system is

The closed loop transfer function of a unity negative feedback system is 100/(s2+8s+100). Its open loop transfer function is:

Consider the circuit shown below. Consider A: Current-shunt feedback B: Current-series feedback C: Voltage-shunt feedback D: Voltage-series feedback Which of the above are present?

As unity feedback system has a forward path transfer function G(s) = K/s(s+8) where K is the gain of the system. The value of K, for making this system critically damped should be

A system with unity feedback having open loop transfer function as G(s) = K(s+1)/s3+as2+2s+1. What values of ‘K’ and ’a’ should be chosen so that the system oscillates ?

The forward path transfer function of a unity feedback system is given by G(s) = 100/(s2+10s+100). The frequency response of this system will exhibit the resonance peak at:
