% We can couple the design of gain on the root locus with a
% step-response simulation for the gain selected. We introduce
the command
% rlocus(G,K), which allows us to specify the range of gain, K,
for plotting the root
% locus. This command will help us smooth the usual root locus
plot by equivalently
% specifying more points via the argument, K. Notice that the
first root locus
% plotted without the argument K is not smooth. We...
1. Root Locus shows graphically how the poles of a closed-loop system varies as K varies. Given the closed-loop system below, obtain the Root Locus for this system. You must explain and show the step-by-step workings and the final root locus plot. You may sketch it first AND then use MATLAB or Excel to show the final plot. Comment on the results.
