The open loop control transfer function of a unity feedback system is given by : G(s) =K/(s+2)(s+4)(s^2+6s+25) Which is the value of K which causes sustained oscillations in the closed loop system? Correct Answer 590

The value of the sustained oscillations is calculated from the Rout-Hurwitz table by equation the quadratic equation=0.

Consider the following statements with respect to the feedback from the control systems: 1. The feedback can improve stability or be harmful to stability if it is not properly applied. 2. The feedback can always improve stability. 3. In many situations, the feedback can reduce the effect of noise and disturbance on system performance. 4. In general, the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located. Select the correct statements.
