  • Patent number: 11303579
    Abstract: A system and method for obtaining frequency-domain admittance/impedance using a few sets of time-series data. Utilizing an Eigensystem Realization Algorithm (ERA) or a dynamic mode decomposition (DMD), the input/output frequency-domain model reflecting voltage/current relationship is identified, and admittance/impedance identification is demonstrated for a grid-connected inverter-based resource (IBR) system. The proposed approach provides a powerful tool to replace the state-of-the-art harmonic injection methodology.

    Abstract: Arrangements for dynamic system control evaluation and issue identification and mitigation are provided. In some examples, data may be received from a plurality of sources. The data may be received in batches at predetermined intervals or time periods, and/or as streaming data. In some examples, a first system control may be identified and a first system control value may be determined for the first system control. A plurality of threshold ranges associated with the first system control may be identified and the first system control value may be compared to the plurality of threshold ranges. Based on the comparing, the first system control value may be mapped to an objective score on a cyber health scale. The objective score may then be evaluated to determine whether an issue is occurring or is likely to occur. If so, one or more mitigation actions may be identified and implemented.

  • Patent number: 11143013
    Abstract: Vibrational behavior of a wellbore operation can be characterized as a vibrational map relating a modeled or sensed vibration level of the operation's equipment to operational parameters of the wellbore operation. The operational parameters can be controllable by settings of the equipment. The map can include multiple contour lines, each representing a set of adjacent coordinates of operational parameters that have the same vibrational level. Tracing a contour line can include determining vibration at a pre-tracing coordinate, adjusting the operational parameters until the vibration level to be mapped is reached at a tracing origin coordinate, then varying the operational parameters while keeping the vibration level constant until the tracing origin or a bound of the operational parameters is reached. Vibration levels having multiple, non-intersecting contour lines can be found by repeating tracing from a different pre-tracing coordinate.

  • Patent number: 11059217
    Abstract: In the formation of a solid object by progressively adding extruded materials to a workpiece, a mechanism is disclosed for transposing the paths by which two or more extrusion nozzles travel to deposit materials. Paralleling a surface contour of the object being formed, the paths for two or more substantially continuous extruded traces are directed in complementary fashion to cause a first extrusion trace to form the object surface while a second extrusion trace is deposited behind the first trace. At another position along the surface contour, the paths of the extruded traces may cross over one another to allow the second extruded trace to define the object surface. Where the first and second traces have a different color or visual appearance, the disclosed mechanism enables fine graphic features to efficiently be integrated into the surface of the object being formed.

  • Patent number: 10969752
    Abstract: Properties of a physical system are measured and used to update estimated states of the system in an iterative manner. At each iteration, a state update weight is assigned for each state and the states are predicted from previous estimated states. System states are predicted from prior estimates and then updated dependent upon the measurements and the state update weights to provide updated estimated states. In addition, a prior covariance matrix of state errors is updated dependent upon the state update weights to provide an estimation error covariance matrix that is consistent with the updated estimated states. The updated state may be equivalent to a weighted sum of a prior estimated state and an initial updated estimated state. The approach provides improvements to a variety of estimators, including least squares estimators and estimators such as the Extended, Schmidt and Unscented Kalman Filters and the Rao-Blackwellized Particle Filter.

The system includes: a data storage interface for receiving alarm activations in data storage, where the recorded alarm activations correspond to alarms; a data processor for: determining, from the recorded alarm activations, time intervals for alarm analysis; and computing similarity measures between the time intervals that depend on the occurrence of the recorded alarm activations in the time intervals, and where the contribution of an alarm activation to the similarity of two time intervals is reduced with an increasing occurrence of the alarm in the time intervals; and a user interface configured to provide pairs of time intervals to an operator of the one or more technical systems that include time intervals with similarity measures indicating similar alarm.

  • Patent number: 10921759
    Abstract: Embodiments are directed to computer methods and systems that build and deploy a pattern model to detect an operating event in an online plant process. To build the pattern model, the methods and systems define a signature of the operating event, such that the defined signature contains a time series pattern for a KPI associated with the operating event. The methods and systems deploy the pattern model to automatically monitor, during online execution of the plant process, trends in movement of the KPI as a time series. The methods and systems determine, in real-time, a distance score between a range of the monitored time series and the time series pattern contained in the defined signature. The methods and systems automatically detect the operating event in the online industrial process based on the determined distance score, and alter parameters of the process (e.g., valves, actuators, etc.) to prevent the operating event.

  • Patent number: 10890882
    Abstract: A method includes obtaining one or more models associated with a model-based controller in an industrial process having multiple actuator arrays and performing spatial tuning of the controller. The spatial tuning includes identifying weighting matrices that suppress one or more frequency components in actuator profiles of the actuator arrays. The spatial tuning could also include finding a worst-case cutoff frequency over all output channels for each process input, designing the weighting matrices to penalize higher-frequency actuator variability based on the model(s) and the cutoff frequencies, and finding a multiplier for a spatial frequency weighted actuator variability term in a function that guarantees robust spatial stability. The controller could be configured to use a function during control of the industrial process, where a change to one or more terms of the function alters operation of the controller and the industrial process and at least one term is based on the weighting matrices.
