Simple mechanical linkages are often unable to cope with the many control problems associated with high performance aircraft maneuvering over a wide flight envelope. One procedure for retaining uniform handling qualities over such an envelope is to i

Efforts to automate the estimation of left-ventricular volume from serial angiocardiograms have neglected the explicit location of the aortic valve line and the ventricle apex. From heuristic considerations of typical aorta-ventricle outlines, an alg

The feasibility of using evolutionary techniques to construct a model for a given process was investigated. Programs were written to synthesize six competing models and to adjust, combine, and eliminate these according to their performance with respe

Two Master's level student projects are described stressing the on-line real time use of a minicomputer as an element of an overall system. Emphasis is placed on using the dedicated minicomputer as an integral part of the system being developed and a

A predictive system was described by Chestnut, et al. [4]. The purpose of this work is to increase the types of plants which can be controlled by such systems by making the fast time model adaptive, and to experimentally compare the random signal beh

An extended Kalman filter with a fictitious noise input is developed for tracking time-varying parameters. An adaptation algorithm is used for adjusting the covariance of the fictitious noise according to the magnitude of the measured residuals and a

Simple mechanical linkages are often unable to cope with many control problems associated with high performance aircraft. This has led to the development of digital fly-by-wire control systems and in particular digital adaptive controllers that can b

A discrete model reference adaptive control algorithm is developed for multi-input, multi-output plants, which does not require explicit on-line identification. Stability of the error between plant and model output is guaranteed even when the conditi

Optimization techniques are applied to feedrate and voltage control in order to improve performance of biaxial contouring systems. This is done by maintaining contour error within a prescribed tolerance while tracking the trajectory in minimum time.

A computer-based proportional-integral (PI) controller has been developed to control arterial oxygen levels in mechanically-ventilated animals. Arterial oxygen saturation is monitored using a non-invasive oximeter and control is effected by adjusting
