A finite-difference method for linearization in nonlinear estimation algorithms
收藏 引用
AUTOMATICA 1997年 第11期33卷 2053-2058页
作者: Schei, TS SINTEF Elect & Cybernet N-7034 Trondheim Norway
Linearizations of nonlinear functions that are based on Jacobian matrices often cannot be applied in practical applications of nonlinear estimation techniques. An alternative linearization method is presented in this ... 详细信息

Hidden Markov model state estimation with randomly delayed observations
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 1999年 第8期47卷 2157-2166页
作者: Evans, JS Krishnamurthy, V Univ Calif Berkeley Dept Elect Engn & Comp Sci Berkeley CA 94720 USA Univ Melbourne Dept Elect & Elect Engn Parkville Vic 3052 Australia
This paper considers state estimation for a discrete-time hidden Markov model (HMM) when the observations are delayed by a random time, The delay process is itself modeled as a finite state Markov chain that allows an... 详细信息

Developing Inferential estimation algorithms using Genetic Programming
收藏 引用
IFAC Proceedings Volumes 1997年 第9期30卷 209-214页
作者: M.J. Willis H.G. Hiden G.A. Montague Dept. Chemical & Process Engineering Newcastle University NEI 7RU United Kingdom
In this contribution, Genetic Programming (GP) is used to develop inferential estimation models using experimental data. GP performs symbolic optimisation, automatically determining both the structure and the complexi... 详细信息

Square-root information filtering and fixed-interval smoothing with singularities
收藏 引用
AUTOMATICA 1999年 第7期35卷 1323-1331页
作者: Psiaki, ML Cornell Univ Sibley Sch Mech & Aerosp Engn Ithaca NY 14853 USA
The square-root information filter algorithm and the related covariance smoother algorithm have been generalized to handle singular state-transition matrices and perfect measurements. This allows the use of SRIF techn... 详细信息

Model structure and numerical properties of normal equations
收藏 引用
IFAC Proceedings Volumes 1999年 第2期32卷 4040-4045页
作者: Brett Ninness Håkan Hjalmarsson Dept. of Elec. & Comp. Eng Uni. Newcastle Fax: +61 2 49 21 69 93 Australia. Dept. Sensors Signals & Systems Royal Inst. Technology S-100 44 Stockholm FAX: +46 8 790 7329 Sweden
There has been recent interest in using orthonormalised forms of fixed denominator model structures for system identification. A key motivating factor in the employment of these forms is that of improved numerical pro... 详细信息

On a nonlinear controller tuning strategy
收藏 引用
IFAC Proceedings Volumes 1999年 第2期32卷 4570-4575页
作者: Jonas Sjöberg Franky De Bruyne Dept of Signals and Systems Chalmers University of Technology 412 96 Gothenburg Sweden Dept of Systems Engineering Australian National University Canberra ACT 0200 Australia
In this work a new algorithm to tune a linear controller for a nonlinear system is presented. The algorithm iteratively minimizes a criterion of the control performance and it can be seen as an extension of the recent... 详细信息
