Abstract : The root-locus technique used in the determination of system response has been a powerful tool for the engineer. Shortcomings of the technique, however, particularly in regard to the locations of imaginary roots and the frequency stability of the system for changes in the system gain, have made a supplementary technique desirable. Such a technique utilizing the projection onto the K minus j omega plane of the three-dimensional root-locus has been developed. The use of the root-locus plot in conjunction with the K minus j omega trace eliminates these shortcomings and provides the engineer with still another tool in his quest for a more complete method of systems analysis.
