An intelligent oxygen injection control system for afterburners which minimizes transient incinerator pollutant emissions while simultaneously minimizing oxygen consumption. A fuzzy logic-based controller utilizes inputs from sensors that measure gas phase pollutant species such as hydrocarbons and carbon monoxide to control oxygen injection and thus minimize pollutant emissions while minimizing oxygen consumption.

Intelligent afterburner injection control to minimize pollutant emissions

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.
