Discrete kalman filter function
WebAs the optimal linear filter and estimator, the Kalman filter has been extensively utilized for state estimation and prediction in the realm of lumped parameter systems. However, the dynamics of complex industrial systems often vary in both spatial and temporal domains, which take the forms of partial differential equations (PDEs) and/or delay equations. … WebSoftware implementation of the continuous-discrete Kalman filter. routines (stabilized Kalman, UDUT) in Bierman (1977). Figure 3.14 should be compared to Figure 2.12. As an illustration of the continuous-discrete Kalman filter, let us supply it to one of the examples we did by discretization in Section 2.4.
