| 摘 要： | 在滑坡的动态监测中通常存在先验几何信息和物理信息,现有的滤波算法并不能够充分利用这些信息,为控制几何观测异常对形变参数估计的影响,提出一种利用滑坡力学状态信息的约束滤波模型.同时,利用约束方程获得有益信息,精确地确定测量的等价权,给出相应的自适应约束抗差滤波算法,并通过实例说明了带有约束的滤波算法更能提高状态参数估计的...

| Abstract: | For the rational use of geometric and physical information of slope, and in order to control the influence of outliers on deformation parameter estimation, a constrained filtering model using mechanical state information of slope is given. At the same time, the algorithm utilizes the useful information in constrained equation to accurately determine the equivalent weights of measurements, thus the relevant adaptive robust constrained filtering algorithm is given.By a pratical example,it is proved that this algorithm can improve the reliability of state parameter estimation. |
