| Abstract: | The problem for recursive estimation of state bounding of a discrete time linear dynamic system in ellipsoidal sets is addressed. A novel method based on optimal bounding ellipsoid (OBE) algorithmic procedure at each stage of updating is presented to improve computational efficiency and practicability. Simulation results and performance comparisons with ROBP algorithm and Kalman filter are also given. |
