Asymptotically optimal filtering in linear systems with fractional Brownian noises

چکیده
In this paper, the filtering problem is revisited in the basic Gaussian homogeneous linear system driven by fractional Brownian motions. We exhibit a simple approximate filter which is asymptotically optimal in the sense that, when the observation time tends to infinity, the variance of the corresponding filtering error converges to the same limit as for the exact optimal filter.

Separation Principle in the Fractional Gaussian Linear-quadratic Regulator Problem with Partial Observation
In this paper we solve the basic fractional analogue of the classical linear-quadratic Gaussian regulator problem in continuous-time with partial observation. For a controlled linear system where both the state and observation processes are driven by fractional Brownian motions, we describe explicitly the optimal control policy which minimizes a quadratic performance criterion. Actually, we sho...
متن کاملFiltering and parameter estimation in a simple linear system driven by a fractional Brownian motion
The problem of optimal ltering is investigated in a continuous time linear Gaussian system where the signal is a xed random variable and the noise driving the observation process is a fractional Brownian motion with Hurst parameter H 2 (1=2; 1). Closed form expressions are derived both for the optimal lter and the variance of the ltering error. Then an application to the determination of the be...
متن کاملControl of Some Stochastic Systems with a Fractional Brownian Motion
Some stochastic control systems that are described by stochastic differential equations with a fractional Brownian motion are considered. The solutions of these systems are defined by weak solutions. These weak solutions are obtained by the transformation of the measure for a fractional Brownian motion by a Radon-Nikodym derivative. This weak solution approach is used to solve a control problem...
متن کاملOn the Infinite Time Horizon Linear-quadratic Regulator Problem under a Fractional Brownian Perturbation
Recently, stochastic models appropriate for long-range dependent phenomena have attracted a great deal of interest and numerous theoretical results and successful applications have been already reported. In particular, several contributions in the literature have been devoted to the extension of the classical theory of continuoustime stochastic systems driven by Brownian motions to analogues in...
متن کاملOptimal Filtering for Linear Systems with Multiplicative and Additive Wiener Noises
The problem of the optimal state estimation is solved for the system described by the continuous, linear, n-dimensional ordinary differential equation with multiplicative and additive Wiener noises. The obtained solution essentially relies on the recently developed optimal filtering theory for Itô-Volterra systems. Copyright c ©2005 IFAC.
