The accurate mathematical model of WIM is difficult to establish because WIM's parameters change with time when they work. 摘要動(dòng)態(tài)稱(chēng)重系統在測量的過(guò)程中為一時(shí)變系統，難以對稱(chēng)重系統建立精確的數學(xué)模型。
STF adds multi-fading factors in EKF, thus it has strong tracking capability and good robustness, and can deal with variation parameter system effectively. 強跟蹤濾波在卡爾曼濾波的基礎上引入了多重漸消因子，使強跟蹤濾波具有極強的跟蹤能力和較好地魯棒性，因此可以很好地解決變系統變參數的問(wèn)題。
