The receiving unit (13b) receives the superimposed signal at the location of the utility consumer B (30). The connection relation estimation units (14a-14c) estimate the connection relation between the utility consumer A (20) and the utility consumer B (30) on the basis of the receiving status of the superimposed signal and/or the received information received by the receiving units (13a-13c).

Abstract: Compensation for an external disturbance can be applied without requiring a model of the external disturbance, and, particularly, the amount of control can be accurately predicted even when the amplitude of a waveform representing changes in a predicted error with respect to time is not constant with respect to time in a case in which the predicted error that is an error between an actually-measured value of the amount of control of a control target and a predicted value periodically changes. A controller compensates a predicted value of the current amount of control using a predicted error of a previous period by taking changes in the amplitude of a waveform representing a predicted error that is an error between an actually-measured value of the amount of control and a predicted value into account.

Abstract: A control device includes a cyclic communication part, a message communication part, and a communication management part. The cyclic communication part performs communication according to a preset cyclic period. The message communication part performs communication that need not conform to the cyclic period. The communication management part manages a communication schedule for the cyclic communication part and the message communication part. When it is detected that control data scheduled to be communicated is data for preferentially selecting communication in the cyclic communication part, the communication management part detects a communication state of the cyclic communication part. When cyclic communication is possible, the communication management part stores the control data in the cyclic communication part, and when cyclic communication is not possible, the communication management part stores the control data in the message communication part.
