Dear editor,Controllability and observability are basic concepts in modern control theory that are based on Kalman filtering (KF)[1, 2]. In particular, observability is closely related to state estimation ability [2–4]. The indicator called observable degree(OD) has been used to quantitatively measure the degree of observability [5–7]. However, limited by

Dear editor,The basic concept of observability is used to express the possibility to recover the state from measurements in modern control theory [1–3]. It is a qualitative parameter,which cannot reflect the observable degree(OD) ability [4,5].Therefore, the OD is presented to quantitatively obtain the function. The quantitative parameter is effective for indicating the exact degree of estimation ability.

采用同步直线电机牵引的高速磁浮列车长定子轨道是不连续的,一般采用长定子模块拼接而成。为了轨道安装的方便及考虑到温度变形效应影响,在相邻长定子模块间留有一定的接缝,这使得相对位置传感器输出的磁极相角信号存在畸变,而且不同长度的接缝导致的信号畸变情况也不同。针对该问题本文采用了一种新型跟踪微分器(TD),用于解决轨道接缝导致的信号畸变问题。通过仿真与实验对模型与算法进行了验证,结果表明新型快速非线性跟踪微分器能较好解决过轨道大、小接缝时的信号畸变问题。
