Webbthe root locus plot at the pole locations associated with the value provided (using a first-order approximation). In the discrete-time case, the constraint is a curved line. Percent Overshoot. Specifying percent overshoot in the continuous-time root locus causes two rays, starting at the root locus origin, to appear. These rays are the WebbRoot Locus sketching rules Wednesday • Rule 1: # branches = # poles • Rule 2: symmetrical about the real axis • Rule 3: real-axis segments are to the left of an odd number of real …
