Almost all Electronics, Electrical and Mechanical systems are now controlled by a¬†controller, which is embedded as a part of the complete system. Such a system is called an¬†Embedded System. Examples are tele-communication systems, chemical-processing plants,¬†transportation systems such as aircrafts and automobiles, bio-medical instruments and home¬†appliances like microwave ovens and washing machines. The characteristics of embedded¬†systems are that they are designed to do some specific tasks often in real time satisfying certain¬†performance requirements. It is achieved through the controllers and software called firmware¬†stored in read only memory of the controller.
The vast majority of control systems built today are embedded, that is, they rely on builtin,¬†special-purpose microcontrollers (digital computers) to close their feedback loops. Some¬†systems may contain large number of controllers. In such settings, controllers often use shared¬†networks to communicate with each other and with large numbers of sensors and actuators¬†scattered throughout the system. The design of embedded controllers and the intricate, automated¬†communication networks that support them raises many new problems- theoretical and practical about¬†network protocols, compatibility of operating systems, and ways to maximize the¬†effectiveness of the embedded hardware. This course will address many such questions and¬†aspects of embedded and networked control.
