  • Patent number: 9568897
    Abstract: A controller system includes at least one computing device operably connected to a process having a target value for a variable parameter. The computing device(s) is configured to control the variable parameter by performing actions including: computing an error between the target value and an actual value of the variable parameter. Based on the error, the computing device(s) may calculate a desired gain adjustment of the variable parameter, and a desired mean adjustment of the variable parameter. A correction signal may be created for modifying the process by: in response to the error being positive, creating the correction signal by adding the desired mean adjustment and the desired gain adjustment, and in response to the error being negative, creating the correction signal by differencing the desired mean adjustment and the desired gain adjustment. A related program product may carry out similar functions.

  • Patent number: 9372020
    Abstract: In a temperature control system using a controlled mix of high temperature pressurized gas and a cooled vapor/liquid flow of the same medium to cool a thermal load to a target temperature in a high energy environment, particular advantages are obtained in precision and efficiency by passing at least a substantial percentage of the cooled vapor/liquid flow through the thermal load directly, and thereafter mixing the output with a portion of the pressurized gas flow. This “post load mixing” approach increases the thermal transfer coefficient, improves control and facilities target temperature change. Ad added mixing between the cooled expanded flow and a lesser flow of pressurized gas also is used prior to the input to the thermal load. A further feature, termed a remote “Line Box”, enables transport of the separate flows of the two phase medium through a substantial spacing from pressurizing and condensing units without undesired liquefaction in the transport lines.

  • Patent number: 9300137
    Abstract: A control system for a distributed power grid includes a simulation module operative to directly interface with operational control of distributed energy resources (DER) to develop and when necessary dynamically modify control inputs of the distributed power grid. By conducting a decentralized and distributed simulation of DER topology (components and their surrounding infrastructure) each distributed control module can simulate control response characteristics of a plurality of DER to determine a control methodology necessary to achieve a desired target. Once developed the same control inputs can be directly applied to physical DER and thereafter monitored to validate performance. Once validated, operational control of the DER is established while ongoing modifications of the control inputs continues in parallel to maintain desired performance.

  • Patent number: 9176483
    Abstract: Techniques are described for controlling the climate in a data center. Using the input of an administrator, multiple desired attributes of a data center (e.g., temperature, energy consumption, costs, or system performance) may be balanced using a utility function that maximizes the utility of the computing systems in the data center according to the administrator's preferences. Additionally, a cooling model is generated that represents the affect of a control parameter (e.g., the fan speed of a CRAC) on the desire attributes of the data center. The cooling model may then be substituted into the utility function to replace the desired attributes. Using this new utility function, the control parameters may be varied such that the maximum utility is achieved.
