    Abstract: A method of controlling a dynamic physical system comprising a plurality of variable quantities. A model of the system comprising a plurality of variables representing the variable quantities, and a plurality of respective rate equations that describe the rate of change of the variables, is obtained. A control term in at least one rate equation from the plurality of rate equations is identified. A rate control function is derived from, for at least one of the variables in the rate equation, the proportion of the variable to the growth rate of the rate equation, and the rate control function is applied to the control term to provide a stabilised control term. The dynamic physical system is then controlled by modifying at least one of the quantities represented by the variables in the control term, so that the control term derived from the modified quantities is substantially the same as the stabilised control term.

  • Publication number: 20140303789
    Abstract: An HVAC system employs a technique built around a system identification/modeling method that determines critical building loads and airflows experimentally without relying on design plans or statistical modeling approaches. Operation includes observing the dynamic response of individual room temperature, in response to a change of inlet air flow conditions (either air flow rate and/or supply air temperature). This empirically-based model enables development of an optimized control approach that minimizes conditioned airflow while meeting required ventilation, thermal, and humidification performance objectives. Building-wide performance is achieved by aggregating empirically determined room-level loads, thus ensuring that the coupled performance objectives can be achieved while minimizing energy use for every space within a building.

  • Patent number: 8844834
    Abstract: Thermal targeting technology is used to continuously adjust boiler target temperature to the minimum necessary to satisfy the required heating load. Responsive to and initiated by a first call for heat, boiler target temperature is reduced by a predetermined amount upon or subsequent to the call for heat. Once the boiler temperature reaches this new target, a call timer is activated. If demand for heat is satisfied before a time set point is reached, the system ceases providing additional heat energy until the next heat demand. Responsive to and initiated by a next call for heat, the boiler target temperature is again reduced by the predetermined amount upon or subsequent to this next call for heat. Each time the heat demand is satisfied within the predetermined time interval, the boiler target temperature is reduced. If heat demand is not satisfied, a thermal boost is provided at set time intervals until the call for heat is removed.

    Abstract: Co-generating energy sources are controlled using a control system that monitors local and remote data. The local and remote data allow for energy management both in the short and long term by comparing the cost of using the co-generating energy source with other available energy sources. Individual co-generating energy sources can have their data aggregated and combined with remote data to allow for predictions of gross demand for energy. The gross demand can be used by an energy utility to plan for future energy needs and to negotiate with energy providers based upon those needs. The energy utility may control the individual co-generating energy sources so as to most cost-effectively meet the needs of the user of the individual co-generating energy source.

The computer data processing system may receive and store reports from multiple users and/or may receive and store reports at different times from a user. Each report may provide information concerning how the user perceives the comfort level of the user's environment at the time the user supplies the information. The computer data processing system may determine and generate the control information for controlling how the environmental control system controls the environment based on the information concerning how each user perceives the comfort level of the user's environment at the time each user provides the information.

  • Patent number: 8838416
    Abstract: An air conditioning system diagnosis apparatus is obtained in which a refrigerating cycle is automatically analyzed and waveform data in messages flowing in a general-purpose network is acquired and automatically analyzed according to the analysis result of the refrigerating cycle, thereby achieving, with a single apparatus, diagnosis and monitoring of errors in the refrigerating cycle and in the general-purpose network. A trigger output portion creates a trigger on the basis of a waveform analysis condition and the analysis result of a packet received from a message analyzing portion; when receiving the trigger, a waveform input portion reads out waveform data stored in a buffer; waveform analyzing portion notifies a synchronization determining portion of the analysis result of the waveform data; the synchronization determining portion searches for the analysis result of a packet synchronized with the received analysis result of the waveform data.

  • Publication number: 20140249680
    Abstract: Systems and methods for limiting power consumption by a heating, ventilation, and air conditioning (HVAC) subsystem of a building are shown and described. A mathematical linear operator is found that transforms the unused or deferred cooling power usage of the HVAC system based on pre-determined temperature settings to a target cooling power usage. The mathematical operator is applied to the temperature settings to create a temperature setpoint trajectory expected to provide the target cooling power usage.
