要約(英語): This paper proposes a controller design method to reduce deterioration of control quality such as instability and degradation of response performance (transient and steady-state responses, etc.) due to packet loss in wireless control systems. In our proposed method, the influence of packet loss to control systems is considered as a disturbance which is an external input causing deterioration of control quality. The proposed method can keep stability and reduce degradation of response performance even if packet loss occurs by considering the characteristics from a disturbance (an external input) to outputs in control design. In particular, this paper clarifies that the influence of packet loss can be modeled as a control-dependent disturbance, and proposes a controller design method that uses this dependency in controller design and does not depend on packet loss rate. Numerical simulation shows advantages of the proposed controller through comparisons with conventional controllers of existing researches.
