Controller tuning is normally based on an initial estimate of the process dynamics, as determined by bump tests Eg: first order plus dead time process dynamics, with dead time, time constant and process gain values A robust controller provides satisfactory and stable control as the process dynamics vary (eg: due to changes in process operating point, or valve wear) over the entire range of operating conditions {Bialkowski, W L EnTech Control}
An adjective commonly applied in marketing literature to information technology products in several ways A robust product can be one that doesn't break easily Thus, an operating system in which any individual application can fail without disturbing the operating system or other applications can be said to be robust Robust is also sometimes used to mean a product or system of products designed with a full complement of capabilities Thus, in the context of the business world, early UNIX systems were not considered as robust as IBM's mainframe operating systems, which were designed for continuous operation with a very low failure rate and features such as automatic backup of file systems
