#### Robust Output Feedback Control for Discrete - Time Nonlinear Systems

(1993)

In this paper we present a new approach to the solution of the output feedback robust control problem. We employ the recently developed concept of information state for output feedback dynamic games, and obtain necessary ...

#### Risk-Sensitive Control and Dynamic Games for Partially Observed Discrete - Time Nonlinear Systems

(1992)

In this paper we solve a finite-horizon partially observed risk- sensitive stochastic optimal control problem for discrete-time nonlinear systems, and obtain small noise and small risk limits. The small noise limit is ...

#### Dynamic Observers as Asymptotic Limits of Recursive Filters: Special Cases.

(1986)

A method for constructing observers for dynamical systems ae asymptotic limits of filters is described. The program is carried out in detail for linear systems, and in addition, an observer is obtained for a class of systems ...

#### Partially Observed Differential Games, Infinite Dimensional HJI Equations, and Nonlinear HControl

(1994)

This paper presents new results for partially observed nonlinear differential games, which are applied to the nonlinear output feedback Hrobust control problem. Using the concept of information state, we solve these ...

#### Robust and Risk-Sensitive Output Feedback Control for Finite State Machines and Hidden Markov Models

(1994)

The purpose of this paper is to develop a framework for designing controllers for finite state systems which are robust with respect to uncertainties. A deterministic model for uncertainties is introduced, leading to a ...

#### Nonlinear Filtering and Large Deviations: A PDE-Control Theoretic Approach.

(1987)

We consider the asymptotic nonlinear filtering problem dx = f(x)dt + SQRT EPSILONdw = h(x)dt + SQRT EPSILONdv, and obtain lim_EPSILON-->0 EPSILONlog q^EPSILON(x, t) = -W(x, t) for unnormalized conditional densities ...

#### Some General Results and Examples on the Design of Observers for Nonlinear Control Systems.

(1987)

We present an observer design for systems with controlled nonlinear dynamics and nonlinear observation. The design is a development of earlier work, which was motivated by nonlinear filtering asymptotics. The basic design ...

#### Output Feedback Risk - Sensitive Control and Differential Games for Continuous - Time Nonlinear Systems

(1993)

In this paper we carry out a formal analysis of an output feedback risk-sensitive stochastic control problem. Using large deviation limits, this problem is related to a deterministic output feedback differential game. Both ...

#### Robust H∞ Output Feedback Control of Bilinear Systems

(1996)

The study of robust nonlinear control has attracted increasing interest over the last few years. Progress has been aided by the recent entension [FM91, Jam92] of the linear quadratic results [Jac73, Whi81] linking the ...
