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 as 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 adapted to receive a diagnostic index 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 is further adapted to evaluate a condition of the process control loop from one or more of the diagnostic indices.

摘要： PROBLEM TO BE SOLVED: To adaptively adjust an output from a predicted model by using a measured value of a process parameter.
SOLUTION: An adaptive inference model is provided with a standard inference model such as a neural network or a natural model which is constituted so that an output for inferring a process parameter is generated, and the output from the inference model is connected to one or a plurality of measured process parameters to generate an adjusted inference process parameter during process operation. Without reforming the inference model itself, the adaptive inference model requires only an insignificant increase of processing capability and a time to reduce or correct non-linear and linear errors at the estimation of a process variable.

摘要： PROBLEM TO BE SOLVED: To provide a method and system for process model identification that enables generation of an acceptable parametric process model even in situations where no process model parameter convergence has been obtained.SOLUTION: A robust method of creating process models for use in controller generation, such as in MPC controller generation, adds noise to the process data collected and used in the model generation process. In particular, a robust method of creating a parametric process model first collects process outputs on the basis of known test input signals or sequences, adds random noise to the collected process data and then uses a standard or known technique to determine a process model from the collected process data.

摘要： PROBLEM TO BE SOLVED: To provide an adaptive process controller which determines a set of continuously scheduled process model parameters which are used to develop controller tuning parameters for controller tuning.SOLUTION: A state-based, adaptive PID controller uses a new technique to determine an appropriate process model to be used to perform adaptive tuning over various operating regions of a plant, and in particular, uses a process model parameter determination technique that enables continuously scheduled process model parameter update over the various plant operating regions or points. The use of this continuously scheduled process model parameter update method provides for smoother transitions between the tuning parameters used in the PID controller during adaptive tuning procedures which are implemented based on changes in the operating region or the operating point of the process, thereby providing for better overall control.

摘要： PROBLEM TO BE SOLVED: To achieve optimization even when a fact that process output exceeds a restriction limit is predicted in multi-variable model prediction control. SOLUTION: A model prediction controller is constituted so as to execute integrated optimization model prediction control. The controller provides the integrated optimization control by using a feedback route to couple the selected output with input having a set point equivalent to the restriction limit of the selected output. The controller holds the selected output as its restriction limit until one of outputs except the selected output reaches or exceeds the related restriction limit for the output. When the output reaches or exceeds the related restriction limit for the output, the controller loosens the set point until the output no longer reaches or exceeds the related restriction limit for the output.

摘要： PROBLEM TO BE SOLVED: To provide a tuning parameter determination method for a process controller. SOLUTION: A process control loop having a tuned controller is simulated and the robustness of the simulated control loop is plotted as a point on a map. During the generation of the robustness map, a set of different tuning parameters in a stable process control loop area is determined and stored and a robustness characteristic corresponding to a loop having a controller tuned in accordance with these tuning parameters is also determined and stored. A user can select a point in the stable area on the robustness map and a set of tuning parameters capable of generating a control loop having a selected robustness characteristic is determined from the previously calculated set of tuning parameters and the robustness characteristic.

摘要： PROBLEM TO BE SOLVED: To reduce the burden of an operator and to use a correct diagnostic tool by collecting the data on the function blocks to decide a function block that deteriorates the performance of a process control system and then analyzing and correcting the decided function block. SOLUTION: A data collection unit 48 collects and stores the variable indexes of function blocks included in a process control network 10, the mode indexes, the state indexes and the limit indexes. Meanwhile, the data which are collected or managed on an Ethernet are sent to an operator work station 13 and can be periodically stored in a long-term memory or a historian 50 and also used for a diagnostic tool 52 that is located at the station 13. The tool 52 detects systematically the problems by means of the action parameters including a variable parameter that is decided by a function block or a device in the network 10, for example, a mode parameter, a state parameter and a limit parameter.
