Rootlocus in matlab
WebRoot Locus for G(s). s = -0.7 + j1.36 for a damping ratio of 0.4559 The dominant pole(s) are the right-most portion of the root locus. This is the part we want to shift left to speed up the system. Clearly, canceling the fast pole at -15.65 and moving it left won't have much effect on the right-most portion of the root locus. Web1. I am having issues trying to get the root locus plot for the following complex transfer function (H): % Ax = b Form A = 1.0e+06 * [0.0713 - 0.0073i,... -1.8793 - 0.0357i]; b = …

WebJul 6, 2024 · In the root locus plot, MATLAB computes the percentage overshoot according to the lines of constant damping ratio (ζ). The problem is that the damping ratio only makes sense for a second order system and the transfer function used (gproc) is not a second-order system since it has 2 zeros and 3 poles.
