In this paper, A novel nonlinear state estimation algorithm called redundant adaptive robust filter (RARCKF) is proposed for the state estimation of the maneuvering target in which the square-root of the cubature kalman filter (SRCKF), like the other traditional Gaussian domain Bayesian filters, cannot achieve high accuracy of state estimation when it suffers from long-standing model errors or the...
This paper presents a six-DOF follow-up tracking scheme for active target satellite tracking. The scheme is mainly composed of a robust tracking algorithm and a six-DOF follow-up control law. Firstly, a relative motion model using osculating reference orbit (ORO) is built and applied to the redundant adaptive robust extended Kalman filter (RAREKF) to form an ORO-based robust method as the tracking...
In order to reduce the energy assumption consumption in long time dynamic positioning control of airship with the influence of wind, the weather optimal dynamic positioning control is brought out. The airship is controlled under certain position and posture with the anti-direction of the wind, then the wind influence are cancelled out by the main thrusters without help of other thrusters. Considering...
Thinking of the characteristic of 4D guidance in civil aircraft cruise, the paper used a method called multi-mode switching, to realize the flight guidance. First of all, we designed different automatic flight modes used in cruise flight, and then choose one mode in the flight course, when the need changes, it will switch to a different mode. The example of the cruise stage guidance was studied. Simulation...
The outcome of probability hypothesis density or cardinalized probability hypothesis density filter is a random finite set at each time step. However, the interesting thing in practice is the tracks of survived targets. In order to get the tracks of survived targets, data association technique should be used to pair existing tracks with the elements of the outcome random finite set at each time step...
A dynamic image fusion scheme for infrared and visible sequence based on region target detection is proposed in this paper. Target detection technique is employed to segment the source images into target and background regions. Different fusion rules are adopted respectively in target and background regions. A limitedly redundant discrete wavelet transform (LR DWT) method is introduced to achieve...
