Plural Controllers Patents (Class 700/20)
  • Patent number: 11003148
    Abstract: Modifications made by multiple controller devices to an environment model describing a shared automated environment can be coordinated. One of the controller devices can be designated as a coordinator, and any controller device other than the coordinator can send an update request to the coordinator. The coordinator can determine whether to accept or reject the requested modification and can report its determination to the requesting controller device. If the coordinator accepts the request, the coordinator can instigate operations to update the environment model across all controller devices of all users. If the coordinator rejects the request, the environment model is not updated. The controller device that made the request can update its local copy of the environment model and roll back the update if the request is rejected.

    Abstract: Systems and methods for orchestrating the operation of energy consuming loads so as to minimize power consumption are described. In some embodiments, the loads can be HVAC, refrigeration systems, air compressors, and the like, and orchestration is effected either directly or by means of the loads' respective controllers. In some aspects, the controllers can be Smart Thermostats and orchestration is effected through a Cloud-based orchestration platform or “COP.” In certain aspects, a COP uses specifically programmed application programming interfaces or APIs to control the operation of a single manufacturer's Smart Thermostats, where the manufacturer provides its own Cloud based control platform through which the COP operates. The COP can similarly orchestrate the operation of two or more manufacturers' Smart Thermostats through their respective Cloud based control platforms. By these and other means, the operation of a variety of energy consuming loads can be more easily and efficiently orchestrated.

The first control device and the second control device are connected to each other. The first and second devices include functional components which implement the functions that control the technical process. The first control device performs the functions in the functional components for controlling the technical process in cycles, thus creating internal states of the functional components. During control of the technical process by the first control device, information about the internal states of the functional components is transferred, distributed over several cycles, to the second control device. The second control device assigns the transmitted information about the internal states to the functional components. In addition, a corresponding redundantly structured automation device is provided.

  • Patent number: 8972031
    Abstract: A higher-level controller can correct measured metrology data with residual error values as reported by a lower-level controller. This results in a more accurate process disturbance estimate. A method of control obtains, based on measurement sample definition, a first process variable of a system under control, determines a residual error using the first process variable and a first set point, controls the system using the residual error, obtains, based on the same sample definition, a second process variable, and adjusts the second process variable using the residual error. The method may also include determining, using the adjusted second process variable, one or more first set points for controlling the system by the low-level controller that may vary in correspondence with the sample definition.

  • Patent number: 8950512
    Abstract: A method and apparatus for estimating the instantaneous rotational speed of a bottom hole assembly at the lower end of a drill string. In one embodiment, a method includes driving the drill string by a drilling mechanism at the upper end of the drill string. A fundamental frequency of stick-slip oscillations suffered by the drill string is estimated. Variations in a drive torque of the drilling mechanism are determined. Known torsional compliance of the drill string is combined with the variations in the drive torque. An output signal representing the instantaneous rotational speed is provided.
