  • Patent number: 10519759
    Abstract: The present disclosure describes the use of growth models and data driven models that are combined for quickly and efficiently modeling SAGD reservoir oil production. Growth function surrogate models are used for efficient and reliable reservoir modeling and production forecasting as opposed to CPU intensive simulations based on finite difference models. A data-driven technique can then compare the growth function surrogate model with real field data to find discrepancies and inconsistencies between the two, allowing for an updates and improvements of the growth function model.

  • Patent number: 10409232
    Abstract: An engineering tool and a method for parameterizing a model-based predictive controller for controlling a process-engineering process. A quality determining module for determining the quality of the model, which contains the model-based predictive controller for the behavior of the process-engineering process that is to be controlled, uses measurement data to ascertain errors in various model parameters as model errors. The weighting factors used to weight manipulated variable changes in a quality criterion are determined by a weighting factor module such that manipulated variable changes of a model-based predictive controller designed taking into account model errors are the same as those of a predictive controller designed based on the assumption of an error-free model. This advantageously results in good performance with simultaneously adequate stability of the controller.

  • Patent number: 10067485
    Abstract: The present invention provides novel techniques for optimizing and controlling production plants using parametric multifaceted models. In particular, the parametric multifaceted models may be configured to convert a first set of parameters (e.g., control parameters) relating to a production plant into a second set of parameters (e.g., optimization parameters) relating to the production plant. In general, the first set of parameters will be different than the second set of parameters. For example, the first set of parameters may be indicative of low-level, real-time control parameters and the second set of parameters may be indicative of high-level, economic parameters. Utilizing appropriate parameterization may allow the parametric multifaceted models to deliver an appropriate level of detail of the production plant within a reasonable amount of time.

    Abstract: In one implementation, an environmental controller operates a cooling system in an electronic device. The environmental controller includes a closed loop control system for operating a cooling fan at a target speed. The environmental controller may select the target speed based on one or more temperature sensors. The environmental controller may select the target speed based on the speeds of additional fans or the fans may be controlled in unison. The closed loop control system includes a proportional weight. When a measured cooling fan speed deviates from the target speed by more than a threshold error value, the proportional weight is constant. As the measured cooling fan speed approaches the target speed, and the threshold error value is crossed, the proportional weight is variable. The variance may be a function of time such as a periodic stair step function.

  • Patent number: 8755981
    Abstract: A method of controlling a transmission includes estimating an expected coefficient of friction of the clutch, estimating a value of an expected torque required to maintain a constant slip of the clutch for a current input torque applied to the transmission, and determining a value of an actual torque applied to the clutch to maintain the constant slip of the clutch at the current input torque. An actual coefficient of friction of the clutch is calculated by dividing the actual torque applied to the clutch by the expected torque applied to the clutch, and multiplying that quotient by the expected coefficient of friction of the clutch. A feed forward torque command is then adjusted based upon the actual coefficient of friction of the clutch to define a revised value of the feed forward torque command, which may then be used to control the clutch for various control operations.

  • Patent number: 8671973
    Abstract: A method of characterizing hysteresis as a function of a device output comprising, applying an input signal across a first input signal range to a device, the input signal inducing a device function having a first output with a first output value range dependent upon the first input signal range. The input signal is further applied across a second input signal range to the device, the input signal inducing the device function to have a second output with a second output value range dependent upon (i) the second input signal range and (ii) device hysteresis. A difference between the second input signal range and the first input signal range is then measured across the first and second output value ranges. A method of operating a mass flow controller valve and a mass flow controller are also contemplated.

    Abstract: A model predictive controller (MPC) for controlling physical processes includes a non-linear control section that includes a memory that stores a non-linear (NL) model that is coupled to a linearizer that provides at least one linearized model, and a linear control section that includes a memory that stores a linear model. A controller engine is coupled to receive both the linearized model and linear model. The MPC includes a switch that in one position causes the controller engine to operate in a linear mode utilizing the linear model to implement linear process control and in another position causes the controller engine to operate in a NL mode utilizing the linearized model to implement NL process control. The switch can be an automatic switch configured for automatically switching between linear process control and NL process control.

  • Patent number: 8649885
    Abstract: Methods and control systems are provided for controlling stage position errors based, in some embodiments, on a selection of frequency components in a stage position error signal. An error frequency representation of a position error signal may be generated in the frequency domain and filtered by selecting one or more desired frequency components. The filtered error frequency representation can then be manipulated according to a control law and transformed back into the time domain to generate a current control signal. The current control signal can then be used to adjust the position of the stage to reduce positioning error.

  • Patent number: 8639437
    Abstract: The present invention discloses a back-propagating intersection collision avoidance (ICA) system for preventing two or more vehicles from colliding at an intersection. The ICA system can calculate predicted positions of the two or more vehicles in the near future, and both the current and future positions can be broadcast to surrounding vehicles using vehicle-to-vehicle communication. For each vehicle, a set of states, for example position, speed, acceleration, and the like, where a collision is imminent can be identified using state information for a local vehicle, a remote vehicle, and a known collision zone for the intersection. If the current states of the vehicles are determined to be in danger of entering the collision zone, the ICA system can control the vehicles to perform evasive driving maneuvers and/or alert the drivers.
