SQUARE ROOT FILTERING VIA COVARIANCE AND INFORMATION EIGENFACTORS
收藏 引用
AUTOMATICA 1986年 第5期22卷 599-604页
作者: OSHMAN, Y BARITZHACK, IY Department of Aeronautical Engineering Technion - Israel Institute of Technology Haifa 32000 Israel
Two new square root Kalman filtering algorithms are presented. Both algorithms are based on the spectral V − Λ of the covariance matrix where V is the matrix whose columns are the eigenvectors of the covariance and ... 详细信息

ASYMPTOTICALLY OPTIMUM recursive PREDICTION ERROR METHODS IN ADAPTIVE ESTIMATION AND CONTROL
收藏 引用
AUTOMATICA 1986年 第2期22卷 237-240页
作者: MOORE, JB BOEL, RK Department of Systems Engineering Research School of Physical Sciences Australian National University Canberra ACT 2601 Australia Visiting Research Fellow (NFWO) Department of Systems Engineering Research School of Physical Sciences Australian National University on leave from an NFWO (Belgium National Foundation for Scientific Research) Research Fellow position at the Rijksuniversiteit Gent Belgium
The challenge taken up in this paper is to devise a parameter identification algorithm for linear, discrete-time, stochastic plants which exploits the strengths of both the extended least squares (ELS) and the recursi... 详细信息

STOCHASTIC APPROXIMATIONS VIA LARGE DEVIATIONS - ASYMPTOTIC PROPERTIES
收藏 引用
SIAM JOURNAL ON CONTROL AND OPTIMIZATION 1985年 第5期23卷 675-696页
作者: DUPUIS, P KUSHNER, HJ Brown Univ Div of Applied Mathematics Providence RI USA Brown Univ Div of Applied Mathematics Providence RI USA
Asymptotic properties of Robbins–Munro and Kiefer–Wolfowitz type stochastic approximation algorithms are obtained via the theory of large deviations. The conditions are weak and can even yield w.p.l. convergence res... 详细信息

TRACKING ERROR-BOUNDS OF ADAPTIVE NONSTATIONARY FILTERING
收藏 引用
AUTOMATICA 1985年 第3期21卷 293-302页
作者: EWEDA, E MACCHI, O CNRS ECOLE SUPER ELECTSIGNAUX & SYST LABF-91190 GIF SUR YVETTEFRANCE
Adaptive filtering with error gradient algorithm and constant step-size is analyzed for a deterministic time variable optimum filtering vector. The unrealistic assumption of independent observations is replaced by a b... 详细信息

OPTIMIZATION WITH RESPECT TO COVARIANCE SEQUENCE PARAMETERS
收藏 引用
AUTOMATICA 1985年 第6期21卷 671-675页
作者: STOICA, P SODERSTROM, T UNIV UPPSALA INST TECHNOLDEPT AUTOMAT CONTROL & SYST ANALS-75121 UPPSALASWEDEN
A general problem involving optimization of a covariance sequence is considered in the paper. One difficulty with this class of problems is to ensure that the covariance sequence is nonnegative definite (in other word... 详细信息

ON 2ND-ORDER FILTER PERFORMANCE
收藏 引用
AUTOMATICA 1985年 第3期21卷 333-336页
作者: WILLMAN, WW Research Department Naval Weapons Center China Lake CA 93555 United States
Monte Carlo simulation is used to compare the numerical performance of a second-order filtering algorithm with those of two previously tested filters in a well-known nonlinear state estimation problem.

Application of the Stochastic Gradient Method to the Control of a Non-Linear Process Modelled as a Markov Chain
收藏 引用
IFAC Proceedings Volumes 1985年 第5期18卷 357-362页
作者: A. Majdoul L.E.E.S.A. Faculte de Science B.P. 1014 Rabat Morocco
Computing the control law for non-linear systems can be facilitated by using a stochastic automaton model. The automaton adapts i5 policy by means of a stochastic gradient algorithm, that depends on the estimation of ... 详细信息

A Multipredictor-Based LQ Self-Tuning Controller
收藏 引用
IFAC Proceedings Volumes 1985年 第5期18卷 137-141页
作者: J.M. Lemos E. Mosca Centro de Anàlise e Processamento de Sinais Universidade Técnica de Lisboa Av. Rovisco Pais 1000 Lisboa Portugal Dipartimento di Sistemi e Informatica Università di Firenze Via S. Marta 3 50139 Firenze Italy
The problem of controlling a plant with unknown and slowly time-varying para meters is considered. In order to make the resulting adaptive controller robust against model mismatching, future bahaviour of the plant is ... 详细信息

PERFORMANCE IMPROVEMENTS OF SELF-TUNING CONTROLLERS BY MULTISTEP HORIZONS - THE MUSMAR APPROACH
收藏 引用
AUTOMATICA 1984年 第5期20卷 681-699页
作者: GRECO, C MENGA, G MOSCA, E ZAPPA, G UNIV FIRENZE DIPARTIMENTO SISTEMI & INFORMAT I-50139 FIRENZE ITALY
The problem of adaptively controlling a linear multivariable plant according to a quadratic cost functional defined over a control horizon of arbitrary length is discussed. In this context, the proposed algorithm, ref... 详细信息

A PERSPECTIVE ON CONVERGENCE OF ADAPTIVE-CONTROL algorithms
收藏 引用
AUTOMATICA 1984年 第5期20卷 519-531页
作者: GOODWIN, GC HILL, DJ PALANISWAMI, M Department of Electrical and Computer Engineering University of Newcastle New South Wales 2308 Australia
This paper presents an overview of the current status of convergence theory for adaptive control algorithms. Rather than giving a comprehensive survey, the paper aims to emphasize the conceptual common ground between ... 详细信息
