摘要： An apparatus is adapted to be used to create software and programming instructions for a distributed process control system having a user workstation remotely located from a distributed controller that controls one or more field devices using control modules. The apparatus includes a computer having a memory and a processing unit as well as a configuration application and a controller application stored on the computer memory to be executed on the processor. The configuration application is further capable of being executed on the user workstation of the distributed process control system to create the control modules for execution by the distributed controller while the controller application is adapted to be executed on the distributed controller to implement one of the control modules during operation of the distributed process control system. In this system, the configuration application, when run on the computer, creates a first control module capable of being used by the distributed controller within the distributed process control system and the controller application causes execution of the first control module within the computer to thereby simulate operation of the distributed process control system. The use of this system enables the simulation and testing of distributed process control system software and control modules without the use of the hardware, e.g., the distributed process controller and field devices, which will ultimately run that software.

摘要： An integrated optimization and control technique integrates an optimization procedure, such as a linear or quadratic programming optimization procedure, with advanced control, such as model predictive control, within a process plant in which the number of control and auxiliary variables can be greater than the number of manipulated variables within the process plant. The technique first determines a step response matrix defining the correlation between changes in the manipulated variables and each of the process variables that are used during optimization. A subset of the control variables and auxiliary variables is then selected to be used as inputs to a model predictive control routine used to perform control during operation of the process and a square M by M control matrix to be used by the model predictive control routine is generated. Thereafter, during each scan of the process controller, the optimizer routine calculates the optimal operating target of each of the complete set of control and auxiliary variables and provides the determined target operating points for each of the selected subset of control and auxiliary variables to the model predictive control routine as inputs. The model predictive control routine determines changes in the manipulated variables for use in controlling the process from the target and measured values for each of the subset of the control and auxiliary variables and the M by M control matrix.

摘要： An operator interface within a process plant includes an execution engine that implements process flow modules made up of interconnected smart process objects that are aware of devices and other entities within the plant and that can perform methods to detect conditions within the plant, especially on a system-level basis. The smart process objects include a display element to be displayed to the operator, data storage for storing data pertaining to and/or received from an associated entity within a plant, inputs and outputs for communicating with other smart process objects and methods that may be executed on the stored and received data to detect plant conditions, including system-level conditions, such as leaks, errors and other conditions. Process flow modules, which may be made up of numerous interconnected smart process objects, may also include flow algorithms associated therewith to calculate mass balances, flows, etc. for the process elements within the process flow modules.
