Effective measurement for successful Statistical Process Control (SPC) implementations across any level of Capability Maturity Model (CMM) is not a very straightforward activity. Based on CMM standard, SPC is only applicable to its higher maturity levels so as to tackle quantitative process management issues like out-of-control process and to point out further areas of process improvements. This study...
The capability to shorten the process of engineering technical systems, from the mission to build the system to the final commissioning of the system, has become a critical factor for company success. This engineering process has become a time and money consuming part of the overall life cycle of a technical system. Common approaches for tackling this problem are the improvement of functions of isolated...
The integration of package units in a SCADA or DCS involves considerable manual effort. Various aspects of automation such as faceplates, states of sequences or interlocks have to be reproduced for the visualization and management of the package unit in the master control system. The integration effort can be reduced using existing technologies, which could also be extended to a modular plug-and-produce...
Wireless communication is already used in process automation for process monitoring. The next stage of implementation of wireless technology in industrial applications is for process control. The need for wireless networked control systems has evolved because of the necessity for extensibility, mobility, modularity, fast deployment, and reduced installation and maintenance cost. These benefits are...
Currently there is a great dependence on industry and society to the use of embedded computer systems, they are present in our daily lives and often we do not realize it. The greatest feature of such systems is the ability to perform very important tasks with little computational resource. Many of these products are considered critical, since in case of failure, may cause catastrophes or large losses...
In almost all industries the processes are nonlinear in nature. The nonlinear systems Preoccupied for study are the conical tank and spherical tank systems that is approximated to a first order equation. The control of level is carried out by using FOPIC technique. Fractional order calculus is a down order calculus having an area of arithmetic that has the derivative and integral from noninteger order...
The related factors affecting the quality of the project are analyzed, the correlation of financial information and factors affecting the quality of the project is elaborated, and this paper analyzes the relationship between financial information and the quality of the project. According to these relations, the related reference formula is proposed, according to these formulas, the broadly engineering...
The motivation of this study is to obtain a single PID tuning formula for different type of processes with enhanced disturbance rejection performance. The simple tuning formula gives consistently better performance as compared to well-known SIMC method at the same degree of robustness for stable and integrating process. The performance of the unstable process has been compared with other recently...
In this paper, aiming at a class of time-delay high-order SISO linear systems in process industries, we propose a PI control strategy based on virtual un-modeled dynamics compensation, this method is based on the traditional PI control method, estimating system's virtual un-modeled dynamics by adopting data-driven control method, then design the compensator to eliminate the un-modeled dynamics' negative...
To deal with the constrained communication between Device net of device layer and Ethernet of operation layer in industrial processes, a semi-physical simulation platform, which consists of industrial process control system, constrained communication transmission module and virtual process control object, is designed and proposed in this paper. Considering thoroughly the problems of packet dropout,...
This paper presents an overview on the evolution of the application of electrical and automation technologies in the industrial processes, with more details in the hot rolling mills for metals. Different aspects are taken into consideration, like electrical motors, power electronics, process control and information management. Finally, a proposal of a target framework for the future possible applications...
This paper presents the principal solution for a real time load control application in the industry under the conditions of open electricity market. The aim of the study is to create the basic concept of a PLC controlled load optimization system for the group of energy intensive machines. The optimized load curve calculations for the specific machine or for the aggregated group of machines in the...
In recent years industries and colleges have had a greater need for improved six sigma training. Presented in the following paper will be an up to date analysis of the current six sigma curriculum being taught here at Bradley University. This paper attempts to address the problem with the lack of educational training engineers have when entering a six sigma improvement process for their given industry...
This study aimed to design an integrated pedagogical approach to advance introductory Process Control Engineering Education through the application of the Technological Pedagogical Content Knowledge (TPACK) framework, and evaluating its impact on student learning. The research is initially being undertaken at Nottingham Trent University, UK but we will next adapt it to a case study in Libya. This...
This paper is devoted to the problem of data transfer rates between automation devices and cloud services. The possibilities of the device connection to the automation systems are described, their time characteristic are determined. The connections are compared and evaluated accordingly to their compliance with the current requirements of Industry 4.0. The decision about the possibilities of their...
Conical Tank is one of the nonlinear processes used in many industries. In this paper various analog PI controllers were designed and analyzed for the conical tank system to maintain the liquid level in tank at the desired value. The level control becomes quite typical due to the nonlinear shape of tank as the rate of rise of water in the narrow part of the tank is high and gets reduce as height increases...
Though industry is one of the major consumers of electricity but Demand Response (DR) research in the industrial sector is relatively immature. The use of wireless technologies as a part of demand response infrastructure in industry has benefits, including increased flexibility of operation and reduced installation and maintenance costs. In this study, a demonstration system of the infrastructure...
This paper presents innovative approach for teaching the subject Process instrumentation at the undergraduate level in Instrumentation engineering as a part of an effective teaching learning process. The approach presented attempts to elicit interest of the students on a continuing basis by illustratively bringing out the application perspective of theoretical concepts through a series of learning...
We examine a two-stage lot scheduling problem with waiting time constraints and distinct due dates. Wafer lots in diffusion or etch processes generally have due dates specified for each process stage. Some lots even have more strict time constraints that their waiting times between two or multiple stages should not exceed specified limits. We also wish to minimize the variation of the waiting times...
This paper presents the effect of various control tuning methods to the controllability of air temperature oven system. The simplest open loop test on actual plant has been performed using a Reformulated Tangent Method (RTM). Three PID tuning rules namely Ziegler Nichols (Z-N), Cohen Coon (C-C), and Chien, Hrones & Reswick (CHR) are used in this work. The plant is connected to Distributed Control...
