Abstract

In this paper, an end-point boundary temperature control approach for runout table cooling used in hot strip mills is presented. The system relies on a linearized model for describing heat radiated to the environment and heat transferred to cooling water. At first, a conventional feedforward control design to control the temperature at the end-point boundary, the only measurable controlled parameter, is presented. Subsequently, a modified control scheme which uses dynamic programming to minimize the temperature error at the end-point boundary is discussed in detail. System performance analysis via simulation is presented for both control schemes. Simulation results show that temperature error minimization by dynamic programming improves system performance.

Temperature control of a continuous, push-type, five-zone, slab-reheating furnace for minimum-fuel usage. Volume I. Text and Appendix A

Technical Report Purdy, D J ; Williams, T J

Investigations are made of temperature control for a continuous, five zone, pusher type, reheat furnace used to heat slabs from the slabbing mill up to the rolling temperature needed for the hot strip mill. Minimum fuel rates needed to achieve required outlet temperature as a function of production rate are determined. A scheme is presented for carrying out the transition from one steady state operating level to another with a near minimium of fuel usage. A method for using this transition scheme on a process control computer is also presented. A specific objective of this thesis is to suggest amore »« less
Use of treated gasification wastewater in a pilot cooling tower: Final report for the period ending June 30, 1986

Technical Report Mayer, G G ; Johnson, M D ; Hetland, M D ; ...

To date, six cooling tower tests have been conducted to evaluate the wastewater treatment and reuse process utilized by the Great Plains Gasification Plant (GPGP) facility near Beulah, North Dakota. The first three tests, Phases I, II, and III, were performed using extracted, steam-stripped gas liquor (SGL) produced in the UNDERC pilot-scale slagging fixed-bed gasifier as makeup. The last three tests, Phases IV-A, IV-B and V, were conducted using GPGP produced SGL as makeup. The final test, Phase V, is the subject of this report. Prior to its use as Phase V cooling tower makeup, the GPGP SGL was solventmore »« less
An inverse dynamic trajectory planning for the end-point tracking control of a flexible manipulator

Conference Kwon, D S ; Babcock, S M ; Book, W J

A manipulator system that needs significantly large workspace volume and high payload capacity has greater link flexibility than typical industrial robots and teleoperators. If link flexibility is significant, position control of the manipulator`s end-effecter exhibits the nonminimum phase, noncollocated, and flexible structure system control problems. This paper addresses inverse dynamic trajectory planning issues of a flexible manipulator. The inverse dynamic equation of a flexible manipulator was solved in the time domain. By dividing the inverse system equation into the causal part and the anticausal part, the inverse dynamic method calculates the feedforward torque and the trajectories of all state variablesmore »« less

De Novo Ultrascale Atomistic Simulations On High-End Parallel Supercomputers

Journal Article Nakano, A ; Kalia, R K ; Nomura, K ; ... - The International Journal of High Performance Computing Applications, vol. 22, no. 1, February 1, 2008, pp. 113-128

We present a de novo hierarchical simulation framework for first-principles based predictive simulations of materials and their validation on high-end parallel supercomputers and geographically distributed clusters. In this framework, high-end chemically reactive and non-reactive molecular dynamics (MD) simulations explore a wide solution space to discover microscopic mechanisms that govern macroscopic material properties, into which highly accurate quantum mechanical (QM) simulations are embedded to validate the discovered mechanisms and quantify the uncertainty of the solution. The framework includes an embedded divide-and-conquer (EDC) algorithmic framework for the design of linear-scaling simulation algorithms with minimal bandwidth complexity and tight error control. The EDCmore »« less
