Multi-sensor multi-rate fusion estimation for networked systems: Advances and perspectives

In industrial systems, the multi-rate sampling strategy has been widely used due to advantage in balancing cost and performance as well psychical characteristics of hardware. Accordingly, analysis synthesis problems systems (MRSs) have received considerable research attentions owing significant engineering background. Among others, state estimation problem, aims estimate system based on contaminated measurement signals, is one most important topics area signal processing. past decades, plenty results obtained for MRSs. The intent this survey provide a timely systematic review with respect available algorithms networked MRSs corresponding fusion methods. First, general state–space model given methods that transform into single-rate ones are introduced. Then, recent advances discussed indices used. Finally, some future MRS problems.
