| Abstract(in English) | According to connecting various things to the Internet, we have been able to control remote things. The system is called Internet of things (IoT). Then the number of information and communication technology (ICT) devices is increasing. We are concerned about the increase of power consumption because of the increase of it. The power-saving networked control systems (NCS) has a sleeping system on the forward and feedback paths. It can realize the decrease of power consumption because of not sending data at certain periods. However, it means that it lets the system lose data. Moreover, a network delay is caused simultaneously, so the performance control can decline. In consideration of these conditions, we regard the data losses because of sleeping as network disturbances and then propose introducing communication disturbance observer (CDOB) into the power-saving NCS for compensating the losses and the network delay simultaneously. Simulations confirm the effectiveness of the proposed method. |
