Model output following control for an Aluminum Plate cooling process with a Peltier device, 2012Co-Authors: Shengjun Wen, Guotao Zhang, Yongping Dan, Dongyun Wang, Mingcong DengAbstract:
In this paper, model output following control based on command generator tracker is considered to realize the control for an Aluminum Plate cooling process with a Peltier device. The Aluminum Plate cooling process with a Peltier device is divided into two parts, that is, one part has the Peltier device and another part has not. The models of the two parts are established respectively, where the heat conduction between the two parts is considered as an inertia delay element in this paper. In order to achieve the satisfactory tracking performance for the process with the delay, the method of model output following control based on command generator tracker is presented in this paper. It is not necessary that the order of the reference model is the same as the actual system. However, instead of the order requirement, the plant must be almost strictly positive real, where the robust parallel compensator is designed to transform the augmented plant into almost strictly positive real. The effectiveness of the proposed methods is demonstrated by the simulation.

In this paper, operator based robust control system design for multi-input multi-output (MIMO) Aluminum Plate thermal process is considered. In details, one class of operator based MIMO system is described and the control system design for the process is given. Based on the proposed design scheme, the system is robustly stable and the desired output tracking performance can be realized. Finally, the theoretical analysis is applied onto a 3-input/3-output Aluminum Plate temperature control process. The effectiveness is demonstrated by simulation result.

Networked non-linear control for an Aluminum Plate thermal process with time-delaysInternational Journal of Systems Science, 2008Co-Authors: Mingcong Deng, Akira InoueAbstract:
This article considers networked non-linear control for an Aluminum Plate thermal process. This is done by using operator-based robust right coprime factorisation approach and Bezout identity to guarantee robust stable networked control system, as well as an operator-based tracking controller to ensure the controlled process output tracking the desired reference input. An experimental result is given for the case of temperature control of the Aluminum Plate thermal process.

Optimal Scheduling for Aluminum Plate Rolling Based on Max AlgebraInformation & Computation, 2009Co-Authors: Hou Wen-mingAbstract:
The Aluminum Plate rolling control system is modeled by max algebra theory.According to production condition rules between the rolling mill and the workpieces,a multi-server/multi-queue model can be constructed for the rolling system. The max-algebra-based closed-loop model of the production line is analyzed,and the influences of different Aluminum Plates rolling queues on the system stable cycle performance is studied.The optimazation aim is to minimize the rolling production cycle,and the scheduling queue is studied with perturbation analysis.The optimal scheduling plan for Aluminum Plate rolling can be obtained with the period assignment method.
Robustness performance of Aluminum Plate rolling system based on maximum algebra method, 2009Co-Authors: Hou Wen-mingAbstract:
In order to decrease Aluminum Plate rolling time and enhance system robustness, the Aluminum Plate rolling multi-queue system was analyzed by max algebra theory and queue theory. Based on the technologic route rules and process condition rules between machine tools and work pieces, a rolling control system closed-loop model was built up by max algebra and the computing character of maximum algebra was introduced. Moreover, multi-server/ multi-queue system model for rolling process was built. The concepts of parameter perturbation and robustness were defined. The influence of system stable cycle in different kinds of Aluminum Plates rolling queues was studied by the product lines closed-loop model. Taking the minimum production period as the optimal object, perturbation analysis was made to evaluate the different queues performances. The results show that the optimal scheduling plan can be obtained on the basis of period assignment method. The perturbation performance in scheduled queues can be compared by maximum algebra theory. The system robustness is improved and the total system running time is decreased. The system efficiency is improved by the scheduling method.
