Provided are a control system, a control device, a control method, and a control program capable of performing stable control so that an offset does not occur with respect to a target value even when dead time is relatively long. A control system includes a target device configured to be controlled based on a control signal, a sensor configured to measure a physical quantity of the target device, and a control device configured to send the control signal to the target device based on a command value and the physical quantity and perform feedback control. The control device includes a calculator that calculates a compensation amount of the control signal based on a set value of dead time and a model of the target device. The calculator calculates the compensation amount including a first term based on the control signal and a second term based on the compensation amount calculated in the past, and changes a coefficient of the second term from a predetermined value to less than the predetermined value when a predetermined condition is satisfied.

The present disclosure provides a method for managing a pipe network of natural gas. The method may comprise: obtaining pipe network information of natural gas in at least one area, the pipe network information including a running time of a system of the pipe network of the natural gas and gas leakage information of the pipe network; extracting feature information based on the running time and the gas leakage information; predicting a maintenance time of the pipe network by inputting the feature information into a maintenance time prediction model.

A building system of a building including one or more memory devices having instructions thereon, that, when executed by one or more processors, cause the one or more processors to manage a plurality of entitlements for a plurality of subscriptions of one or more buildings with a building entitlement model, receive a first request to perform a first operation for a first subscription and a second request to perform a second operation for a second subscription, and implement the first operation on first computing resources of a first zone based on the building entitlement model in response to a first determination that the first subscription has the first entitlement and implement the second operation on second computing resources of the second zone based on the building entitlement model in response to a second determination that the second subscription has the second entitlement.

A building system of a building including one or more memory devices having instructions thereon, that, when executed by one or more processors, cause the one or more processors to receive a command to perform an action for an entity. The instructions cause the one or more processors to identify a service configured to perform the action based on a building graph, the building graph including a plurality of nodes and a plurality of edges, wherein the plurality of nodes represent entities of the building, the service, and one or more other services, wherein the plurality of edges represent relationships between the entities and communication actions of the service with the one or more other services and cause the service to perform the action by causing the service to perform one or more communication actions with the one or more other services indicated by the building graph.

A building system of a building including one or more memory devices having instructions thereon, that, when executed by one or more processors, cause the one or more processors to store a digital twin of the building comprising a graph data structure, the graph data structure comprising a plurality of nodes representing entities of the building and a plurality of edges between the plurality of nodes representing relationships between the entities of the building. The instructions cause the one or more processors to receive an modification to the digital twin of the building, generate a change feed event of a change feed, the change feed event recording the modification to the graph data structure, and synchronize, based on the change feed event, an external digital twin of the building of an external system with the digital twin of the building by communicating with the external system.

A building system of a building including one or more memory devices having instructions thereon, that, when executed by one or more processors, cause the one or more processors to receive a query for information of a building graph of the building from a system, the query including an indication of an entity and an indication of an event associated with the entity. The instructions cause the one or more processors to query the building graph with the indication of the entity and the indication of the event associated with the entity for the information of the building graph and generate a query response based on the information and provide the query response to the system.

[Solving means] A remote-control apparatus, including a measurement value receiving unit for receiving a measurement value related to equipment from a local-control apparatus configured to control the equipment; a calculating unit for calculating a control value corresponding to the measurement value received by the measurement value receiving unit and a delay amount, by using a model configured to calculate a control value that should be used for control of the equipment when there is caused control delay including communication delay with the local-control apparatus from a delay amount corresponding to the control delay and a measurement value; and a control value transmitting unit for transmitting the control value calculated by the calculating unit to the local-control apparatus, is provided.
