Do the following using MATLAB: a. Display a root locus and pause. b. Draw a close-up of the root locus where the axes go from 2 to 0 on the real axis and 2 to 2 on thee nayinaaxy axis c. Overlay the 10% overshoot line on the close-up root locus. d. Select interactively the point where the root locus crosses the 10% overshoot line, and respond with the gain at that point as well as all of the closed-loop poles at that gain. ·e. Generate the step response at the gain for 10% overshoot.
