    摘要: In a process control system, the hidden properties of a catalyst are estimated by including those properties in hidden states within a state space model and solving the state space model based on measurable inputs and outputs of the process. The process may include defining a state space model for a process having a catalyst state comprising a hidden catalyst property; defining a set of empirically measurable input variables for the state space model, defining a set of output variables for the state space model, measuring a set of input values corresponding to the set of input variables; measuring a set of output values corresponding to the set of output variables; and estimating the hidden catalyst property based on the input values, the output values, and the state space model.

    摘要: In a process control system, the hidden properties of a catalyst are estimated by including those properties in hidden states within a state space model and solving the state space model based on measurable inputs and outputs of the process. In one embodiment, a method for controlling a process of the type that utilizes a catalyst comprises the steps of: defining a state space model for the process, the state space model including a catalyst state comprising a hidden catalyst property; defining a set of input variables for the state space model, wherein the input variables are empirically measurable properties of the process; defining a set of output variables for the state space model, wherein the output variables are empirically measurable properties of the process; measuring a set of input values corresponding to the set of input variables; measuring a set of output values corresponding to the set of output variables; and estimating the hidden catalyst property based on the input values, the output values, and the state space model.

    摘要: Deviations associated with a process system are identified, such as by identifying deviations of process variables or production measurements from target values. A graphical display is generated that identifies at least some of the deviations and one or more characteristics associated with the deviations. For example, the graphical display includes a time axis, and each deviation is associated with a bar positioned in the graphical display to identify a start time and an end time of the deviation along the time axis. Also, each bar may include one or more indicators (such as patterns, colors, or shadings) that identify the one or more characteristics (such as an economic impact and/or a cause) of each deviation identified in the graphical display. In this way, a user can, among other things, identify when deviations from target values occur, durations of the deviations, and economic impacts and/or causes associated with the deviations.

    摘要: In an embodiment, a system and method are described that enable a display of a parallel coordinate plot. Such a parallel coordinate plot includes a plurality of parallel axes, and each of the parallel axes represents a variable. The display further includes one or more polygonal lines connecting values of the variables of the parallel axes. The system and method further enable a display of information about an additional variable on the parallel coordinate plot by varying the property of the one or more polygonal lines.

An indicator of how a current data point compares to the historical data may be placed on one or more of the data density graphs. In some examples, data falling outside a threshold contour of historical data density may represent a new or an abnormal situation, and such data and/or a contour plot having such data may be highlighted in a graphical display.
