Using SysML to Model Layered System Interfaces

To produce accurate system architecture descriptions, it is essential to be able to describe interfaces between system elements at different levels of abstraction and from different perspectives at the same time. For example, the connection from system A to system B may be viewed at a high level as...

Articles: Motion Control

Every system design presents a unique set of specifications regarding cost, space, time-to-market, and other factors. Designers must therefore make tradeoffs to meet these requirements, such as opting for a higher...
