Correct knowledge of noise statistics is essential for an effective estimator in maneuvering target tracking. In practice, however, the noise statistics are usually unknown or not perfectly known. To deal with the estimation problem in linear discrete-time systems with Markov jump parameters, where the measurement noise covariance is unknown, a novel approach is presented in this paper. This approach...
To obtain a better performance of trajectory tracking for hypersonic glide vehicles (HGVs), this paper focuses on enhancing the accuracy of tracking model, an effective method with a modified tracking model is proposed. Firstly, according to the skip glide trajectory of HTV-2, a simplified trajectory model is established to describe the periodical characteristic of the trajectory. Secondly, a modified...
