This is often used to control the dynamic behavior of the system. Examples of feedback can be found in most complex systems, such as engineering, architecture, economics, thermodynamics, and biology. Negative feedback was applied by Harold Stephen Black to electrical amplifiers in 1927. Arturo Rosenblueth, a Mexican researcher and physician whose seminal 1943 paper Behavior, Purpose and Teleology, according to Norbert Wiener, set the basis for the new science of cybernetics proposed that behavior controlled by negative feedback, applied to either animal, huma
