摘要： A method of diagnosing an adaptive process control loop includes measuring process control loop signal data, generating a plurality of process control loop parameters from the process loop signal data and evaluating a condition of the adaptive process control loop from one or more of the plurality of process control loop parameters. The process control loop data is generated a a result of a normal operation of one or more process control devices within the adaptive process control loop when the adaptive process control loop is connected on-line within a process control environment. A self-diagnostic process control loop includes a diagnostic tool (602) adapted to receive a diagnostic index (610, 604) pertaining to a process control loop parameter for each component of the process control loop and for the complete process control loop. Each diagnostic index is generated from signal data by a corresponding index computation tool. The diagnostic tool (602) is further adapted to evaluate a condition of the process control loop from one or more of the diagnostic indices.

摘要： A system and method for controlling a process includes simulating the process and producing a simulated output (MVss,CVss) of the process, developing in an optimizer 504 a set of target values MVt, CVt, AVt, based on measured inputs MV, CV, AV from the process and based on the simulated output from the process simulator, and producing multiple control outputs configured to control the process based on the set of target values during each operational cycle of the process control system. The simulated outputs include one or more predicted future values up to the steady state of the process.
