#### 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 ...

#### Priority-First Minimum Cover Approach to Diagnostics with Application to Injection Molding.

(1987)

A new methodology is being proposed for application to diagnostics in manufacturing problems. The approach adopts a minimum cover approach where we propose that the requirements for priority and consistency as will be later ...

#### Introduction to Manifolds, Lie Groups, and Estimation on the Circle.

(1987)

These lecture notce introduce some basic concepts concerning smooth manifolds and Lie groups, since they are often the natural mathematical setting for studying nonlinear estimation and control problems. After reviewing ...

#### Design of Resilient Processing Plants. New Characterization of the Effect of RHP Zeros.

(1987)

Right Half Plane (RHP) zeros restrict the achievable closed loop performance independent of controller design. A new characterization of all achievable closed loop set-point/output transfer matrices is provided in terms ...

#### Probability of Capture and Rejection of Primary Multiple-Access Interference in Spread-Spectrum Networks.

(1987)

The probability of capture is evaluated for the situation in which several transmitters use the same spread-spectrum code to contend for the attention of a single receiver. The first stage in the capture mechanism is that ...

#### Filtering Results for A Joint Control-Decoding Problem in Optical Communications.

(1987)

We consider a doubly-stochastic time-space Poisson-process model for a direct-detection receiver in an optical communication system. Using a Bayesian decision approach to specify the design of the receiver, we encounter a ...

#### The Acoustic Features of Speech Phonemes in a Model of Auditory Processing: Vowels and Unvoiced Fricatives.

(1987)

The acoustic features of three types of stimuli (a harmonic series, naturally spoken vowels, and unvoiced fricatives) are analyzed based on the response patterns they evoke in a model of auditory processing. The model ...

#### 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 ...
