    Abstract: Robustly stabilizing controller bandwidth for a controlled mechanical system is determined as a function of the system's estimated inertia and dominant system parameters that define constraints on the bandwidth. In one or more embodiments, a bandwidth model is derived that defines a relationship between robustly stabilizing controller bandwidth and system gain over a range of reasonable system uncertainties. Using the model, a suitable controller bandwidth can be determined for a given motion control system given only estimates of the system gain and the dominant parameters(s) that constrain the bandwidth. In an example two-inertia system, the system gain and dominant parameter can comprise system inertia and mechanical coupling stiffness, respectively. Accordingly, estimates of the system inertia and coupling stiffness can be provided to the system, which determines a suitable controller bandwidth for the motion control system characterized by the estimates.

The controller gain kl is increased to get the closed loop system to the stability limit. At this stage the controller ultimate gain ku and the sustained oscillation period period Tosc of the controlled value are assessed. It is assumed that the controlled system dynamics can be approximated by the first order filter with dead time model. The following formulas allow to estimate the first order filter time constant F(1) and the coefficient ?=L/T=(arcctg(?oscT))/(?oscT) where L is the dead time constant of the controlled system model.

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.

  • Patent number: 8504331
    Abstract: A method is disclosed of identifying or fixing the value of the parameters (aerodynamic data) of a pre-determined set of equations forming the aerodynamic models of an aircraft in various configurations, so as to minimize the variance between the values anticipated by using these aerodynamic data, and reference data in cases of known configurations, includes the use of learning or optimization methods to determine at least one portion of the parameters' values. The method includes storing database data, choosing an optimization method or a neural network method, breaking the identification down into several partial identifications, carrying out successive partial identifications, validating the values found for the aerodynamic model's parameters or iterating the method according to a threshold criterion determined on the value of variances between the reference data and the values measured by the identified model.

  • Patent number: 8489209
    Abstract: A method is provided for analyzing and diagnosing a large scale process automation control system having a plurality of control loops. Assessments for pre-defined key performance indicators (KPIs) are automatically generated for control, process and signal sections of each control loop. The automatically generated assessments of the pre-defined KPIs may be displayed in a graphical user interface (GUI) of a computer. A user may change the automatically generated assessments of the pre-defined KPIs. Different data views may also be displayed in the GUI. The data views include time series trends for measured process variable, controller output, controller set point and error, as well as controller parameter clustering views in two-dimensional and three-dimensional plots.

  • Patent number: 8463411
    Abstract: One or more techniques are provided for the sharing of variable trajectories between multiple controllers in a control system. In general, the present technique is based upon the sharing of predicted desired variable trajectories between multiple controllers requiring a common input variable. In one embodiment, a common input variable is shared between two controllers, wherein one controller is tuned to have dominant control with regard to the shared variable. Each controller determines and communicates their own desired trajectory for the shared variable to the other controller and in doing so, the constraints associated with each controller are shared and honored by the other controller. Based on the communicated trajectories, the dominant controller may exercise control over the shared variable, thus improving overall process control.

    Abstract: Embodiments of techniques and systems for managing performance of a computing system are described. In embodiments, parameters may be received describing control variables for a computing system, workloads that are performed on the computing system, and performance metrics for the computing system. An experimental plan may be generated for modifying the control variables during execution of the computing system and observing performance metrics during this execution. The recorded observations may then be used in to determine one or more relationships between the control variables and the performance metrics. Relationships between the control variables and a desirability function associated with performance of the computer system may also be determined. These relationships may be displayed in visualizations to a user, and may be used to by the user to select values for the computing system which increase the desirability function. Other embodiments may be described and claimed.

  • Patent number: 8406919
    Abstract: A quality regulating apparatus and method is disclosed which operates on a product stream having an incoming product stream quality level so that an outgoing product stream quality level provided by the apparatus follows a target quality level so that it is better than the target quality level providing a maximum yield. The apparatus includes a conveying device, a product stream imager, an inspection engine, a routing engine, and an object diverting station. In operation, the inspection engine and routing engine cooperate in a manner so that objects classified as defective are intentionally passed to the output product stream when their inclusion maintains the quality level of the first output product stream at a level that is better than or equal to the target quality level.

  • Patent number: 8387256
    Abstract: Method of reducing performance variability of membrane scaling devices. Scaling device performance uncertainty is reduced, thereby reducing the scaling safety factor, by specifying a narrow range or subset of the set of all qualified manufactured membranes for installation into scaling devices. In certain embodiments, the scalability factor is reduced by determining where within the performance distribution a particular membrane lies, and adjusting the scaling factor accordingly.

  • Patent number: 8352048
    Abstract: A method and an electronic device for compensation of the hysteresis of a pneumatically driven fitting having an electropneumatic valve. The electropneumatic valve is driven by a position regulator and is used in a closed control loop for position regulation of a switching element of an pneumatic actuating drive for operation of the fitting. Hysteresis of the pneumatically driven fitting is compensated for by the position regulator via at least one hysteresis correction factor. The control-engineering compensation for the hysteresis is carried out separately for a first basic case of starting or reversing a switching element and for a second basic case of continuous movement of the switching element, such that a dominant static friction is compensated for in the first basic case and the dominant sliding friction is compensated for in the second basic case, and the pneumatic actuating drive operates the switching element matched thereto.

  • Patent number: 8301498
    Abstract: A video demographics analysis system selects a training set of videos to use to correlate viewer demographics and video content data. The video demographics analysis system extracts demographic data from viewer profiles related to videos in the training set and creates a set of demographic distributions, and also extracts video data from videos in the training set. The video demographics analysis system correlates the viewer demographics with the video data of videos viewed by that viewer. Using the prediction model produced by the machine learning process, a new video about which there is no a priori knowledge can be associated with a predicted demographic distribution specifying probabilities of the video appealing to different types of people within a given demographic category, such as people of different ages within an age demographic category.
