This paper provides a context within which the role of human factors engineering (HFE) for Naval ship design may be understood. HFE is defined and its history as part of engineering design teams is traced. The role of HFE in ship systems design is defined, and the HFE Technology for Ships Program, managed by SEA 061R, is described. The rationale for inclusion of HFE in the design process is presented, the methodology whereby it is incorporated into the design process is detailed, methodology to assess the application of HFE is outlined, and the benefits that will accrue as a result of inclusion of HFE considerations in the design process are documented. The counterpoint to inclusion is illustrated through instances of design-induced human errors. A specific application of HFE in the acquisition process is illustrated through use of the Landing Craft, Air Cushion HFE program plan. The difficulties which may be encountered as the size of the target system expands are described. Potential roadblocks to the required incorporation of HFE are examined for their source and possible ameliorative steps.

His responsibilities have included directing a number of studies on advanced SES concepts managing activities defining mission/cost effectiveness of military and commercial SES's including defining the operational benefits and enhanced survivability characteristics of cargo SES's for high speed military sealiftfor NA TO and Southeast Asia

This paper will present the results of a marketing, engineering, and economic analysis of advanced marine vehicles done by IMA Resources, Inc. and RMI, Inc., in support of a Maritime Administration project to study “Multimode Express Shipping”. The study was conducted in 1981 and examined the economic benefits of using advanced marine vehicles as express cargo vessels in domestic and international service. Commodity characteristics, desirable express carrier rates, and potential high payoff service and route alternatives were identified. Advanced marine vehicles were surveyed and sized to meet desirable deadweight and block speed objectives. The costs of operating these craft on a variety of trade routes were calculated using an advanced marine vehicle economic analysis program. Revenues, expenses, break-even, profit and loss, cash flow requirements, tax summary and economic indicators (i.e., cost/ton – mile, etc.) were projected over the expected life of the vehicles as was return on investment. Traffic density and market penetration considerations narrowed the field of choice to smaller sized advanced marine vehicle carriers (i.e., 50 and 250 ton deadweight) and to three international and five domestic routes.

Design of Digital State-Feedback controllers Using a CAD Package

引用

IFAC Proceedings Volumes 1982年第1期15卷 101-108页

作者： Chr. Schmid G. Juen Department of Electrical Engineering Ruhr-University D-4630 Bochum Federal Republic of Germany Institute of System Dynamics and Control Engineering University of Stuttgart D-7000 Stuttgart Federal Republic of Germany

CAD methods for multivariable discrete-time optimal state-feedback control systems including integral output feedback and observers with known and/or unknown inputs are discussed. Depending on the performance index different combinations of feedback and feedforward controllers are obtained. The effects of measured and observed disturbances and set point changes are shown by simulation studies of a 14th order steam generator subsystem. The implementation of theory, algorithms and software is sketched.

A lattice implementation of the extended least-squares algorithm was recently developed. The convergence of that algorithm depends on a positive real condition, a fact which limits its usefulness in some applications. In this note the lattice equivalent of the recursive maximum likelihood algorithm is derived. This technique does not require the positive real condition and is suitable for modeling and prediction of general ARMA time-series.

An Adaptive Computer control Method in Hot Strip Rolling

引用

IFAC Proceedings Volumes 1981年第2期14卷 2495-2500页

作者： T. Katayama T. Morita M. Konishi Department of Applied Mathematics and Physics Faculty of Engineering Kyoto University Kyoto 606 Japan System Control Research Section Asada Research Laboratory Kobe Steel Ltd. Kobe 657 Japan

A new adaptive computer control model in hot strip rolling has been developed. The main idea is to improve the accuracy of the force calculation and to balance the inter-stands load distribution by introducing a new adaptive systems based on the gradient technique and a stochastic approximation-type algorithm. The feasibility of the new method is demonstrated by off-line simulations using actual rolling data. The comparison of the new method with the conventional method shows that the accuracy of the force calculation can be remarkably improved, especially in down-stream stands where the reduction in draft is rather small, and that the inter-stands load distribution can be well balanced.

Nuclear reactors are controlled by movable control rods made of neutron absorbing materials. These rods are driven by control rod drive mechanism which is directed by servo-control circuit. New drive mechanism was developed. Magnetic plunger connected with control rods in guide tube is exerted by the magnetic coil outside of the guide tube. Special circuit for precise positioning of the plunger relative to the coil have been developed. The drive mechanism has no vessel penetration such as rotary seal or sliding seal, so that no leakage of primary cooling water of high radioactivity was reached.

作者： S. Vittal Rao D. P. Atherton R. Balasubramanian System Dynamics and Control Research Group Electrical Engineering Department University of New Brunswick Fredericton NB Canada

Several research workers [1-5] have studied the problem of designing suboptimal/near optimal regulators for high order plants. The implementation of the sub-optimal controllers has the advantage that a significant saving in computational effort may be realized with a small deterioration in system performance. The methods available for designing suboptimal controllers for large scale systems may be classified in the following broad categories: i) State vector partitioning methods [1] ii) Singular perturbation methods [2] iii) The use of aggregated reduced order models [3] iv) control law reduction [4] The methods (ii) through (iv) yield good results if the original system eigenvalues are clearly separable into dominant and non-dominant modes. However, the state vector partitioning method is applicable to all cases. In this method suboptimal controllers are derived by partitioning the given system state vector into two or more parts and then solving the matrix Riccati equations for the subsystems. Finally, the controllers for each partitioned system are combined linearly to provide a suboptimal control for the original system. Meditch [1] introduced a set of constant matrices for deriving the lower order subsystems. These matrices play a crucial role in obtaining the suboptimal controller. However, no systematic procedure has been given for choosing these constant matrices apart from the work of Reddy and Rao [5] who presented a procedure for a multi-output system making use of Crossley's [6] canonical form. In this paper a method is presented to derive systematically the constant weighting matrices from the modal matrix of the original system. These constant matrices can be termed as aggregation matrices. It is proved that the resultant suboptimal closed loop system is always stable with this particular choice of aggregation matrices.
