Abstract
A method and system of determining tuning parameters for use in tuning a controller used in a process control loop for a motor and associated load. The method includes providing tuning parameters, applying an excitation test signal, receiving frequency response data to determine phase and gain margins, creating an instability region defined by a bounded area that connects the phase and gain margins with a boundary on a gain vs. phase plot, assigning and applying cost functions, and computing stability determinations.
