Abstract:

Root locus plots in the s plane are practically limited to a span of two decades. In problems where some poles are very close to the origin, while other poles or zeros are at very large values of s, sufficient resolution of the locus may not be available in two decades of the s plane. However, root loci can be plotted in the 1n s plane using as many decades as desired and whichever are desired. The ESIAC is an analog computer which constructs root locus plots in the 1n s plane. A mathematical analysis of the 1n s plane, a simple method of plotting root loci in the 1n s plane, and several practical examples demonstrating the technique are presented. Construction of root loci by this method requires the use of one template.
