    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (282 KB)

    When material is fed through a rolling mill, the rolls of the stand should exert a sufficient pressure on the material so as to reduce the thickness of the material by a certain amount while maintaining the interstand tension of the material at the desired level. An adaptive self-tuning controller for the control of a rolling mill is presented. The controller is designed on the basis of a time-ser... View full abstract»

    Although various control schemes have been successful in controlling mean arterial blood pressure by infusing a vasoactive drug, the simultaneous control of cardiac output and blood pressure by multiple drug infusion has to-date received little attention. To this effect, this paper describes the design of an automated multiple drug delivery system. The proposed computer-based controller combines s... View full abstract»

  • Model Identification in Exercise Physiology

    Publication Year: 1983, Page(s):27 - 30
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (348 KB)

    Model identification for respiratory control during exercise motivates a modeling perspective concerning input design, structure identification and statistical justification. From this perspective, a functional model is proposed and initially tested in two "quiet breathers" and two "noisy breathers" using a pulse input in cycle ergometer work-rate. The results indicate that an input design that yi... View full abstract»

  • Noise Models in Respiration

    Publication Year: 1983, Page(s):31 - 35
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (380 KB)

    The physiologically based fluctuations observed in experiments involving the human ventilatory response to inhaled carbon dioxide are incorporated in a number of stochastic models. Least squares is compared with maximum likelihood methods for different noise models. Multiple local maxima observed in the maximum likelihood technique motivate the development of a new method to detect the global maxi... View full abstract»

  • Optimality Principle in Respiratory Control

    Publication Year: 1983, Page(s):36 - 40
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (444 KB)

    A classical dilemma in the physiological control of human respiration is that the increase in respiratory ventilation during muscular exercise is normally sustained despite little increase in the intensities of chemical stimulation to breathing. To account for this phenomenon, it has recently been suggested that the control law governing the ventilatory output may be an optimization rather than re... View full abstract»

    Publication Year: 1983, Page(s):41 - 45
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (406 KB)

    This paper discusses the pulmonary washout tests and some of the considerations involved in applying optimal experimental design theory to these tests. Optimal inputs are described as binary sequences. For a given set of parameters the optimal input is determined by minimizing the determinant of the covariance matrix (J). Optimal inputs for a given set of parameters are determined using a modified... View full abstract»

    The present study demonstrates that accurate estimates of cardiac output and other related cardiopulmonary parameters can be obtained noninvasively from respiratory data by driving the system with an appropriately designed ventilatory input. This input consists of a sequence of 3 larger-than-normal breaths and a 12-second breathhold performed 3 times in succession over a total duration of 1 minute... View full abstract»

    The development of MMS (modular modeling system) by EPRI is reported. The purpose was to supplement existing transient-analysis codes like RETRAN and RELAP by providing an efficient, economical, user-friendly code to be used by utility engineers for long-term and scoping safety analysis of both fossil and nuclear power plants. As a result of extensive validation and trial user-group experience, it... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (587 KB)

    EASY5 is the result of a development effort of more than 10 years duration. Analysts at Being perceived the need for a single software tool to support both nonlinear simulation and linearized analysis of dynamic systems. Prior to the development of EASY5 it was necessary to build and maintain two models of a dynamic system: a linearized model used for controls analysis and design and a nonlinear m...

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (511 KB)

    A dynamic model of the MSUS standard coal-fired unit was developed using EPRI's Modular Modeling System (MMS) code. A simplified control system model was used to help reveal the need for more sophisticated control strategies. The control system was also designed for operation in either a constant throttle pressure or a sliding throttle pressure control mode. Transient results showed that reheat st... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (506 KB)

    This paper describes a dynamic model of a carbureted spark-ignition engine. The model responds to throttle, air/fuel, EGR, spark advance, and load torque inputs to provide manifold pressure, exhaust air/fuel, brake torque, and engine speed outputs. The dynamic aspects of the model are due to time delays and integration. Nonlinear relationships are incorporated to predict engine performance over a ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (529 KB)

    The problem of automatic steering control of a large tanker in a seaway is formulated within the framework of linear quadratic Gaussian (LQG) control theory. Wave disturbance are characterized by shaping filters, and Kalman filters are designed using these disturbance noise models.

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (387 KB)

    This paper presents a formulation of the frequency shaped optimal estimator and investigates the role of the measurement noise shaping function in this estimator. This shaping function creates transmission zeros and affects the singular values of the estimator transfer matrix, which can be used to improve control system robustness. The resulting estimator design technique has been applied to the e... View full abstract»
