Feedback

feedback FEEDBACK The exhibition at the New York Hall of Science helped me to seek how machines and living things sense changes in their environment and how they adapt as a result. A wide range of mechanical and biologic systems use the same essential method, called feedback. At the museum I was subject to pedal an airplane propeller, direct a chain on a spinning windmill and observe an old-fashion steam engine as I explored self-sensing machines and how they work.

The organization for the automatic regulating of an electrical, mechanical, or biological system by sending part of its yield as input is feedback. An example of feedback is a governor of an engine. If the fixture of the engine exceeds a certain limit, the governor reduces the supply of burn down and hence the speed decreases. Electronic control systems employ feedback extensively. In voltage and current systems, part of the output is used as a control input, and this provides the system with self-regul...If you want to get a full essay, order it on our website: Orderessay
