Abstract
The power efficiency of an electric motor driven load including an adjustable speed drive is improved through use of a fuzzy logic controller to provide a power efficiency signal. A fuzzy rule base controls sequential power changes based on a determination of the effect of previous changes to meet load demands on a reduced power input basis.
