  • Patent number: 11307549
    Abstract: A system includes a plurality of control devices that respectively control the states of a plurality of apparatuses and are connected to each other via communication lines. When each of the control devices determines a state target value of its own apparatus using the current state indicator value of the own apparatus, and the distributed controller input which is a function of the state indicator value of an apparatus adjacent to the own apparatus and the state indicator value of the own apparatus, the control gain which adjusts contribution of the distributed controller input to the state target value is determined based on a communication delay time between the control devices.

  • Patent number: 11269315
    Abstract: A distributed control system includes a plurality of control units that controls respective units of a plurality of devices, and a communication network that includes a communication line that connects the control units. A control unit of each of the devices is configured to determine a state target value, according to consensus control of a multi-agent system, by using a current state index value of a self-device, and a difference between a latest state index value of an adjacent device received from a control unit of the adjacent device, and a latest state index value of the self-device received from the control unit of the adjacent device.
