On parameterization design for linear observers

Journal of the Franklin Institute, 2003
In the paper linear, continuous-time, finite-dimensional control systems with constant coefficients are considered. The definition of state observer is given. Next, based on a reduced-order state observer, a new observer parametrization is proposed and discussed in detail.

Observer Design for Systems with Diffusion

IMA Journal of Mathematical Control and Information, 1991
Summary: Finite-dimensional approximate observers are designed for one-dimensional diffusion processes described by a scalar partial differential equation of the parabolic type. In the design, the observer's accuracy can be traded off against its dynamical order and the number and type of the required measurement.

Observer design for descriptor systems

IEEE Transactions on Automatic Control, 1999
Two detectability notions are introduced for the most general class of linear descriptor systems. Necessary and sufficient conditions are derived for the detectabilities and for the existence of observers. Depending on existence conditions satisfied, the observers can be either in the familiar Luenberger form or in a generalized form, i.e., in ...

Observer Design of Bilinear Systems

Journal of Dynamic Systems, Measurement, and Control, 1983
In this paper, recent results on the observer design of bilinear control systems (BLS) are first reviewed. Different design procedures are examined with respect to their associated observer error behavior. A new class of BLS observers which can be designed via pole-assignment algorithms is then presented.

Design of observers

1989
This chapter shows that an estimate of the states x can be obtained using an asymptotic observer whenever the system is observable. We also showed that an observer of order (n-m) is adequate to estimate all the states. We also defined a minimal order observer to estimate linear functions of states.

Contraction and observer design on cones

IEEE Conference on Decision and Control and European Control Conference, 2011
We consider the problem of positive observer design for positive systems defined on solid cones in Banach spaces. The design is based on the Hilbert metric and convergence properties are analyzed in the light of the Birkhoff theorem. Two main applications are discussed: positive observers for systems defined in the positive orthant, and positive ...

Observational Study Design I

BMJ, 2011
Researchers investigated whether the use of oral or transdermal hormone replacement therapy was a risk factor for stroke. Data were taken from the General Practice Research Database, a computerised database of anonymised longitudinal medical records collected prospectively in primary care. A cohort of women was identified, aged 50-79 years with records

Linear Observers Design and Implementation

2014 ASEE Zone 1 Conference Proceedings, 2014
In this paper we show how to implement full- and reduced-order observers using the software packages for computer aided control system design MATLAB and SIMULINK. As a matter of fact, we show how to implement a linear system and its observer, represented by their state space forms, using the SIMULINK state space blocks.

Crossover designs with correlated observations

Journal of Biopharmaceutical Statistics, 1998
Crossover designs are widely used in different medical investigations where a number of treatments have to be compared. Sequences of treatments are given to subjects, and in practice the observations within each subject are likely to be correlated. This paper is concerned with the construction of crossover designs for such cases.
