【摘要】:可觀測(cè)性分析是建立系統(tǒng)誤差估計(jì)模型的一個(gè)必要前提。針對(duì)二維平面中系統(tǒng)誤差與目標(biāo)狀態(tài)聯(lián)合估計(jì)模型的可觀測(cè)性問(wèn)題,采用可觀測(cè)矩陣研究系統(tǒng)的可觀測(cè)性。文中先建立了二維平面內(nèi)目標(biāo)的運(yùn)動(dòng)模型以及雷達(dá)的觀測(cè)模型,同時(shí)構(gòu)建了系統(tǒng)可觀測(cè)矩陣,通過(guò)判定可觀測(cè)矩陣的奇異性研究了系統(tǒng)的可觀測(cè)性問(wèn)題,并且給出了可觀測(cè)度的Maple計(jì)算程序。最后,建立了典型的仿真環(huán)境,通過(guò)仿真分析了有無(wú)傳感器量測(cè)誤差情況下系統(tǒng)誤差的可觀測(cè)性及可觀測(cè)度的特點(diǎn)。
[Abstract]:Observability analysis is a necessary prerequisite for the establishment of a systematic error estimation model. Aiming at the observability of the joint estimation model of system error and target state in two-dimensional plane, the observability of the system is studied by using observable matrix. In this paper, the motion model of the target in the two-dimensional plane and the observation model of the radar are established. At the same time, the observable matrix of the system is constructed, and the observability of the system is studied by judging the singularity of the observable matrix. The Maple program of observable measure is given. Finally, a typical simulation environment is established, and the observability and observability of the system error in the case of sensor measurement error are analyzed by simulation.
