Consider a negative unity feedback control system KG(s): K(s + 10) s(s+5)(s+ 6) (s+ 8) Using Matlab, write a code to plot the root locus of this system. Copy and paste your code as well as the root locus graph.

Need help only with parts D and E and no matlab help required, just computation

QUESTION 3 Consider a unity negative feedback control system. Assume that the plant G(s) does not have an integrator and you are using a proportional compensator K. You want to increase the closed-loop step tracking performance. Currently, the steady- state tracking error of the closed-loop system with K=K_old to a unit step signal is 0.1. You would like this error to be reduced to 0.02 with a new proportional compensator K=K_new. How does the proportional gain have to change to make this possible? We assume that the closed-loop is stable for all values of the proportional gain. Do not guess as incorrect answers will incur a penalty. K_new = 6.33 K_old K_new = 5.44 K_old K_new = 5 K_old K_new = 4.66 K_old

Consider the following control system: R |Ke s+1 + or- What is the unit-step response for negative feedback, withc = 1.0? This is one out of five questions on the same control system. A C() = 0.5(1 -e") B C() = 0.5(1-e*) C() = 1- e- D C) = 1-e05t
