Root-loci 11 - using root-loci for proportional design
Listen now
Description
Indicates how root-loci can be used to indicate achieveable performance and to select the desired value of gain. The focus here is on simple paper and pen computations and estimation and it is shown how relatively crude estimation, based on root-loci sketches can give values of compensator gain very close to the ideal answer. Similar concepts were covered, but using MATLAB tools, in videos 2-4.

Parts of the real axis are nearly always on the root-loci and it can be very insightful to mark these domains. This video shows how this is done by inspection and reinforces with numerical examples.
