WebFeb 19, 2024 · theta = (pi)/n where n is the total number of root locus branches approaching/leaving the point (breakaway/in point). If there are 2 branches, let's say … WebIf a branch on the real axis lies between a pair of poles, the root locus must break away from the real axis somewhere between the poles. Similarly, if a branch on the real axis lies between a pair of zeros, there must be an entry point between that pair of zeros. Rule 5 As K gets very large, P - Z branches go to infinity.
