Process Control Designing Processes And Control Systems For Dynamic Performance


Material balance is applied to the system to generate a dynamic model of the system. The tank levels are assumed to stay constant because of the overflow nozzle and hence there is no level control involved.




process control designing processes and control systems for dynamic performance



An important class of linear/quadratic optimal control problems, the solution of which can reduce plant operating costs enormously, is that concerned with the regulation of Class "0"* processes. Such processes are very common in the chemical and process industries generally. Within wide limits, such a process will often run smoothly, no matter what values of process input or type of control strategy are employed.......


The Department of Mechanical and Aerospace Engineering offers curricula in aerospace engineering and mechanical engineering at both the undergraduate and graduate levels. The scope of the departmental research and teaching program is broad, encompassing dynamics, fluid mechanics, heat and mass transfer, manufacturing and design, nanoelectromechanical and microelectromechanical systems, structural and solid mechanics, and systems and control. The applications of mechanical and aerospace engineering are quite diverse, including aircraft, spacecraft, automobiles, energy and propulsion systems, robotics, machinery, manufacturing and materials processing, microelectronics, biological systems, and more.


Aerospace engineering is characterized by a very high level of technology. The aerospace engineer is likely to operate at the forefront of scientific discoveries, often stimulating these discoveries and providing the inspiration for the creation of new scientific concepts. Meeting these demands requires the imaginative use of many disciplines, including fluid mechanics and aerodynamics, structural mechanics, materials and aeroelasticity, dynamics, control and guidance, propulsion, and energy conversion.


The mechanical engineering program is designed to provide basic knowledge in thermodynamics, fluid mechanics, heat transfer, solid mechanics, mechanical design, dynamics, control, mechanical systems, manufacturing, and materials. The program includes fundamental subjects important to all mechanical engineers.


Features of the dynamics field include dynamics and control of physical systems, including spacecraft, aircraft, helicopters, industrial manipulators; analytical studies of control of large space structures; experimental studies of electromechanical systems; and robotics.


The program is developed around an integrated approach to manufacturing and design. It includes study of manufacturing and design aspects of mechanical systems, material behavior and processing, robotics and manufacturing systems, CAD/CAM theory and applications, computational geometry and geometrical modeling, composite materials and structures, automation and digital control systems, microdevices and nanodevices, radio frequency identification (RFID), and wireless systems.


The program features systems engineering principles and applied mathematical methods of modeling, analysis, and design of continuous- and discrete-time control systems. Emphasis is on modern applications in engineering, systems concepts, feedback and control principles, stability concepts, applied optimal control, differential games, computational methods, simulation, and computer process control. Systems and control research and education in the department cover a broad spectrum of topics primarily based in aerospace and mechanical engineering applications. However, the Chemical and Biomolecular Engineering and Electrical Engineering Departments also have active programs in control systems, and collaboration across departments among faculty members and students in both teaching and research is common.

The written exam enables students to demonstrate understanding, and apply knowledge and skills learnt to solve engineering problems. Coursework assignment provides students more time to think about larger issues and provide engineering solutions to them. This will also allow them to work as a team to handle more substantial problems.Coursework 1 - Theory-based assignment on designing control systems, studying the dynamic response and doing stability analysis will be given. Individual/team assignment with a report that has a maximum of 1500 words/student.

For nearly 20 years, Yokogawa has provided hundreds of APC licenses and consulting & engineering services for a variety of process units. Yokogawa understands that tight, yet flexible integration with APC and DCS results in more profitable operations, and that regulatory control stabilization is important as a baseline for a control hierarchy.


Our all inclusive Platform for Advanced Control and Estimation brings multi-variable control, quality estimation, complex custom calculations, and operator user interface design all into one application; in doing so, dramatically reducing deployment time and simplifying maintenance for robust performance.


Automatic Step Testing is designed to excite the plant for full dynamic response while continuing process control and economic optimization. The powerful identification and modeling tools allow engineers to quickly extract the dynamic model from the plant responses.


Having sequenced multiple processors (controller, estimator, etc.) and all the supporting functions into the same environment (including customization of the user interface to the control application), our platform empowers control engineers to rapidly develop APC applications. This holistic environment platform drastically reduces the application development time.
