Motivation: Recent Developments
Microelectromechanical Systems (MEMS)
- makes it possible to fit large numbers of sensors and actuators into small areas
Smart Structures
- distributed sensors and actuators are incorporated into the natural structure of an object
- strain sensors and PZT actuators embedded in a composite panel for reducing vibrations, monitoring fatigue, or controlling the shape of a flight surface
Inexpensive Microprocessors
- makes it feasible to distribute microprocessors over a large control network, giving sensors and actuators access to local computing power
