Quantized model predictive security control for switched systems suffered by external disturbance and denial‐of‐service attacks.

For the switched systems, the investigation of quantized model predictive security control (MPSC) suffered by denial‐of‐service (DoS) attacks and disturbance with a completely unknown bound is the emphasis of our study. According to whether the quantizer is saturated, the control process is divided into two stages, and the corresponding differentiated quantization rules and control laws are designed. To resist DoS attacks and external disturbance, a unified architecture integrating network and local loops is proposed. The switch rules of the control loops determined by the decision unit are further designed depending on the acknowledgment‐based protocol. A constant upper bound of performance index is gotten by adding a novel coefficient in which. Then designing the model predictive control (MPC) is changed to minimizing a constant. Below this, the sufficient conditions guaranteeing the exponential decay of the closed‐loop system are obtained. At last, the effectiveness of our methods is testified by a two‐tanks system.
