Web27 May 2024 · There are 11 rules that, if followed correctly, will allow you to create a correct root-locus graph. Rule 1. There is one branch of the root-locus for every root of b (s). Rule 2. The roots of b (s) are the poles of the open-loop transfer function. Mark the roots of b (s) on the graph with an X. Rule 3.
Web16 May 2015 · A root locus plot is simply a plot of the s zero values and the s poles on a graph with real and imaginary coordinates. This method is very powerful graphical technique for investigating the effects of the variation of a system parameter on the locations of the closed loop poles. Khalid Saeed Al-Badri Follow
