| 英文摘要 |
| In this paper, an improved multi-channel algorithm is designed to schedule parallel processes of Kalman
filters. The goal is to schedule the transmission of sensor measurements for all processes to meet individual estimation
error requirements with the least communication channels occupied. Our algorithm includes the following methods: A fast
cycle estimation method based on the squeeze method, which accelerates the search for transmission cycles significantly;
An off-line schedule method based on the Buffer Scheme, which is suitable for scheduling transmissions with multiple
communication channels; An on-line reschedule method, which utilizes idle channels against transmission losses and adjusts
the transmission sequence quickly in case of process requirement changes. The effect of the algorithm is verified by
simulations. |
