Automating the Physical World with Linux, Part 3: Designing around System Failure
I hope this series ``Automating the Physical World with Linux'' has been enlightening to those new to the field of control automation. We've covered some essential concepts: building on simple algorithms such as those for lawn sprinklers, a control system can grow in complexity to control and monitor complicated tasks. Pairing Linux's well-established networking capabilities with such a coupled and distributed system allows coordinated automation functions over a large geographic area (such as our lavish resort). A control-system designer must also consider how vulnerable a system is to failure; system failures need to be identified and detected, and the customer may need to dictate how this is to occur.
