An improved constrained dynamic matrix control for temperature in an industrial coke furnace

open access: yesMeasurement + Control, 2019
In order to derive the feasible control law of the constrained model predictive control scheme, quadratic programming has been introduced as an effective method. It is known that the typical performance index for model predictive control strategies under

Solving Quadratic Fractional Programming Problem

open access: yesInternational Journal of Applied Mathematical Research, 2013
In this paper the Quadratic fractional objective programming problem (QFPP) with linear constraints, has been defined and developed. The special case for this problem was solved by using the Wolfe’s method and a modified simplex approach, by suggesting an algorithm for each method to solve the problem. The computer application for algorithms was tested

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Neural-Dynamic Based Synchronous-Optimization Scheme of Dual Redundant Robot Manipulators

open access: yesFrontiers in Neurorobotics, 2018
In order to track complex-path tasks in three dimensional space without joint-drifts, a neural-dynamic based synchronous-optimization (NDSO) scheme of dual redundant robot manipulators is proposed and developed. To do so, an acceleration-level repetitive
