Artificial Intelligence, Fuzzy Logic and Control 225Chapter 6Artificial Intelligence,Fuzzy Logic and ControlWhen a machine performs an act or task that seems to haverequired intelligence, it is called an artificially intelligentact. Intelligence is defined as both the ability to learn fromexperience and the ability to adapt to a surrounding environment.The field of artificial intelligence (AI) involves the use of machinesthat try to duplicate various acts of intelligence that humans canperform.Artificial intelligence is concerned with the development and deploymentof machines that mimic human behavior. It includes the followingareas:• expert systems,• robotics,• vision,• natural language processing, and• artificial neural networks (ANN).Of these, expert systems and ANNs will have a greater impact on HVACcontrol.The study of intelligence in humans and animals helps us understandbetter how to build intelligence into machines. Also, studyingmachines that demonstrate intelligence helps us to understand humansand animals.Intelligence can be demonstrated in several ways:• learning from experience,• adapting to changes in an environment,• receiving and processing vision, speech, and other inputs to obtainspecific information,©2001 by The Fairmont Press, Inc.
