| Abstract: | By monitoring items ,the number of optimization and location optimization from three aspects of the optimal sensor placement , the research status of optimal sensor placement was summarized . The sensor location optimization was emphatically discussed based on modal observability and the injury identifiable criterion ,and the sensor placement rule ,layout methods and evaluation criteria were systematically introduced . Meanwhile , the relations of different layout methods and technology evolutions were compared ,and the advantages and disadvantages were also analyzed .Finally ,the deficiencies of methods of the optimal sensor placement were pointed out ,the technology trends of optimal sensor placement were prospected . |
