Proving Control System Performance
Identifying methods of measuring system performance against project goals can be as important as identifying the goals themselves.

Цитата:
It used to be straightforward. When new instrumentation or automatic control applications were needed, the necessary equipment was purchased, installed, and commissioned. When it was running smoothly, everyone moved on to the next project. It’s not that simple anymore—performance usually has to be proven.
In an advanced control system project, performance testing picks up where basic commissioning leaves off. It tests the operation of the control system as an integrated entity against its functional objectives. Identifying indicators and methods of measuring and testing system performance against project goals can be as important as identifying the goals themselves.
A statistically valid test plan provides a rigorous mechanism for testing system performance. It provides results that allow a user and vendor to share project risks and rewards, to their mutual benefit.
Why test performance?
Achieving basic operation is virtually never an issue—all reputable vendors will ensure that transmitters will measure and transmit signals, that a DCS will communicate and function according to its configuration and programming, and that final actuators will respond to their control signals. So, aside from a healthy curiosity, what are the reasons for performance testing?
