Abstract

Root locus analysis/synthesis is an extremely powerful tool used in classical control system design. Its results can be used to check stability, speed of response, and system damping. However, the solutions to root locus problems can be extremely difficult to obtain in digital control system because the poles are in close proximity. Optimized algorithms will be presented which circumvent this problem and allow for fast, accurate z-plane root locus plots. Prompting for data entry, minimum memory in-place computations, and very little processing requirements yield an easy to use, highly efficient program.
