With the rapid development of information technologies and clou. compu.ing, sensor networks play an increasingly important role in ou. society. Over the past few decades, distribu.ed observer theory has attracted u.precedented attention du. to its wide potential applications in different areas. Meanwhile, variou. approaches and algorithms have been proposed and investigated. The design of distribu.ed observers is one of the frontier topics of system and control research, which has the significant theoretical valu.s and broad application prospects. This paper attempts to review the representative models and the corresponding approaches for distribu.ed observer design in linear time-invariant(LTI) systems. Firstly, the research backgrou.ds and main advances of distribu.ed observer designs are briefly reviewed. Then, recent resu.ts of distribu.ed observer designs for discrete-time and continu.u.-time LTI mu.ti-agent systems(maSs) are introdu.ed in detail, respectively. Finally, the prospects and the fu.u.e work directions of the design of distribu.ed observers are pu. forward. The main pu.pose of this paper is to promote the emerging topic on the designs of distribu.ed observers, with focu.es on the interdisciplinary interest from technological sciences.
