Abstract

An approach of PID controller design for an automatic voltage regulator(AVR) excitation system based on the improved dominant pole placement method was proposed.First

the time domain performance specifications were transferred into the requirements on the dominant poles.Then by introducing a pre-filter

the interval of KP was obtained using the root locus technique to constrain the post-dominant poles within the desired region in the complex plane.The subinterval satisfying the desired maximum se...
