Network based H_∞ Filtering via Imperfect Measurement Output

摘要

This paper is concerned with the network based filtering problem via imperfect measurement output which includes the quantization and sampling caused by the sensor and the packet dropout and transmission delay caused by the network. The packet dropout and transmission delay are only affected to the measurement at only sampling instants owing to the sampling effect by sensor. In addition, when packet dropout is occurred, the last received data is used in the filter. Finally, simulation results are given to illustrate the validity of the proposed methods.
