| 英文摘要 |
| The optimal estimation problem is studied for networked control systems subject to random measurement
delays and without packet loss. With the given probability distribution of the delays, a new model is proposed to describe
the delay measurements. In order to solve the estimation problem, the measurement model with delays is written as an
equivalent multiple channel measurement with each channel has a single constant delay. The optimal estimator is derived
by using a reorganized innovation analysis approach, and is given in terms of Riccati difference equations. A simulation
example illustrates the efficiency of the proposed method. |
