Properties of the Root Locus

The root locus method is an invaluable tool for analyzing higher-order systems without needing to factor the denominator of the transfer function. A pole of the system is identified when the characteristic polynomial in the transfer function's denominator equals zero.

To determine if a point lies on the root locus, the criterion involves ...

A pole is identified when the characteristic polynomial in the transfer function's denominator equals zero.

The criteria for a point to be on the root locus are that the total angle contribution ...
