  • Patent number: 9817375
    Abstract: According to various implementations, a demand response (DR) strategy system is described that can effectively model the HVAC energy consumption of a house using a learning based approach that is based on actual energy usage data collected over a period of days. This modeled energy consumption may be used with day-ahead energy pricing and the weather forecast for the location of the house to develop a DR strategy that is more effective than prior DR strategies. In addition, a computational experiment system is described that generates DR strategies based on various energy consumption models and simulated energy usage data for the house and compares the cost effectiveness and energy usage of the generated DR strategies.

  • Patent number: 9764469
    Abstract: Aspects of the generation of new robotic motion trajectories are described. In one embodiment, a new robot motion trajectory may be generated by gathering demonstrated motion trajectories, adapting the demonstrated motion trajectories into robot-reachable motion trajectories based on a joint space of a robot model, for example, and generating motion harmonics with reference to the motion trajectories. Further, one or more constraints may be specified for a new goal. The weights of the motion harmonics may then be searched to identify or generate a new motion trajectory for a robot, where the new motion minimizes discrepancy from the demonstrated motion trajectories and error due to the at least one constraint. In the new motion trajectory, the degree to which the constraints are satisfied may be tuned using a weight. According to the embodiments, new motion variants may be generated without the need to learn or review new demonstrated trajectories.

    Abstract: A method for establishing a power profile for a computing device and then using that profile for future power calculations and cost savings estimates after the implementation of a selected power scheme in the computing device is disclosed. This is accomplished by establishing a power profile on a model computing device and then matching that profile to other machines that are similar in configuration. Each tested machine has a power profile that is recorded and saved in cloud based memory storage. A striated matching methodology is utilized to provide the best profile match for each target machine in the enterprise which allows for accurate power calculations for each machine based upon similar original target machine profiles. Once power calculations are done for target machines based on the established profiles, power schemes can then be deployed across an enterprise computing landscape and power calculations taken again to determine potential power savings.

  • Patent number: 9329584
    Abstract: A system, program and related computer implemented method for selecting a controller and constructing it to automate one or more processes is provided. The method comprises the steps of: constructing a controller from a plant described by an LPV model to which a scheduling parameter is given by: a) calculating one or more ? gaps and a mean value of each candidate of a plant parameter vector of said LPV model based on a requirement of preselected constraints; b) choosing a candidate via information gathered by proof based on the magnitude of differences between the ? gaps; c) converting the LPV model into LMI and finding controllers, according to an H? criterion, at all combination end points of a maximum value and a minimum value of the plant parameter vector thus chosen; and d) choosing and constructing said chosen controller for said plant.

  • Patent number: 9300141
    Abstract: Methods and systems provided for creating a scalable building block for a virtual power plant, where individual buildings can incorporate on-site renewable energy assets and energy storage and optimize the acquisition, storage and consumption of energy in accordance with a value hierarchy. Each building block can be aggregated into a virtual power plant, in which centralized control of load shifting in selected buildings, based on predictive factors or price signals, can provide bulk power for ancillary services or peak demand situations. Aggregation can occur at multiple levels, including developments consisting of both individual and common renewable energy and storage assets. The methods used to optimize the system can also be applied to “right size” the amount of renewable energy and storage capacity at each site to maximize return on the capital investment.

  • Patent number: 9280146
    Abstract: A device receives a control system model that includes a fixed portion that models elements of a control system to be controlled and a tunable portion that models elements of the control system used to control the elements modeled by the fixed portion. The device receives information that identifies a tunable parameter of the tunable portion of the control system model, a hard constraint associated with the control system model, and a soft constraint associated with the control system model. The hard constraint identifies a first constraint that is to be satisfied, and the soft constraint identifies a second constraint that is to be reduced. The device calculates a parameter value for the tunable parameter by applying an optimization algorithm to the control system model, based on the control system model, the tunable parameter, the hard constraint, and the soft constraint. The device provides the parameter value.

  • Patent number: 9246721
    Abstract: A digital up-converter (DUC) circuit for performing digital channel filtering of an incoming baseband digital signal. The proposed circuit reduces the complexity of the channel module filter of the DUC. This is achieved by taking advantage of the structure of the underlying symbol waveforms carried by the incoming baseband digital signal which have one or more known discontinuities comprising random amplitude and/or phase. Namely, the channel filter module is activated only for the digital samples located around the known discontinuities and is deactivated for the remaining digital samples. Further, the switching of the channel filter module from one state to another can be performed according to a smooth function so that further discontinuities are not introduced in the incoming baseband digital signal. A method and a computer program are also disclosed.

  • Patent number: 9152134
    Abstract: A closed-loop control device for a process, in which a dead band element is connected upstream of a linear dynamic controller to reduce actuating interventions in the steady control state. If a control deviation (e) of the control loop exceeds a first threshold value (s1), then the dead band element is automatically deactivated, where a control deviation (e1) passed via the dead band element is uninfluenced by a set dead band in the inactive state. If the control deviation (e) then undershoots a second threshold value that is less than the first threshold value, then the dead band element is automatically re-activated. This reduces the energy consumption and wear of an actuator and improves the control behavior with regard to steady-state accuracy and the control behavior of the control loop.
