Once production of your article has started, you can track the status of your article via Track Your Accepted Article. Help expand a public dataset of research that support the SDGs. This international journal covers the application of control theory, operations research, computer science and engineering principles to the solution of process control problems. In addition to the traditional chemical processing and manufacturing applications, the scope of process control problems involves In addition to the traditional chemical processing and manufacturing applications, the scope of process control problems involves a wide range of applications that includes energy processes, nano-technology, systems biology, bio-medical engineering, pharmaceutical processing technology, energy storage and conversion, smart grid, and data analytics among others. Papers on the theory in these areas will also be accepted provided the theoretical contribution is aimed at the application and the development of process control techniques.

Principles and Practice of Automatic Process Control

Process control and measuring techniques is a modern educational packet containing technical literature and hardware. Our systems are developed and tested in a working environment in line with the demands of modern education. Our program PID-Future together with the interface PF-1 and many different control component in combination provide a package that can handle the most common control processes. Terco Mecha-Kit is a separate modular system for learning the basics of pneumatics and control techniques.

Process control systems PCS , sometimes called industrial control systems ICS , function as pieces of equipment along the production line during manufacturing that test the process in a variety of ways, and return data for monitoring and troubleshooting. Many types of process control systems exist, including supervisory control and data acquisition SCADA , programmable logic controllers PLC , or distributed control systems DCS , and they work to gather and transmit data obtained during the manufacturing process. The PCS can be a relatively simple item with a sensor, often called a primary transducer, that receives an input, along with a controller that processes the input, and a receiver that processes an output. More complicated PCS devices are robotic and perform many tasks. A great number of measurements can be taken on production lines.

Increase productivity. In the light of the growing complexity of machines and plants along with rising engineering costs, efficient engineering is a key Process Control System with Performance You Trust In process plants, the process control system is the interface to the process and thus the key to the optimal added value.

Automatic process control in continuous production processes is a combination of control engineering and chemical engineering disciplines that uses industrial control systems to achieve a production level of consistency, economy and safety which could not be achieved purely by human manual control. It is implemented widely in industries such as oil refining, pulp and paper manufacturing, chemical processing and power generating plants. There is a wide range of size, type and complexity, but it enables a small number of operators to manage complex processes to a high degree of consistency. The development of large automatic process control systems was instrumental in enabling the design of large high volume and complex processes, which could not be otherwise economically or safely operated. The applications can range from controlling the temperature and level of a single process vessel, to a complete chemical processing plant with several thousand control loops.

The performance of your process control system may gradually decline over time because your operators override the system, or your equipment and plant develop faults. You may not be aware that the system is performing badly because maintenance schedules don't always include the right checks to identify problems. If your system is poorly-maintained, your processes won't be operating efficiently and your energy costs will be higher than necessary. The maintenance approach itself may be the cause of many problems. If 'quick fix' breakdown maintenance is carried out in response to equipment failure, underlying problems may never be sorted out and can become permanent.


What are some sample control strategies? m WHAT DOES A CONTROL SYSTEM DO? First, we will discuss two examples of control systems encountered in.


Process control systems monitor industrial processes to make sure they don't vary from pre-set limits. They start corrective action if they find unwanted deviations or abnormalities. The key element of a process control system is the basic closed-loop control. Systems usually include many hundreds of individual control loops, each of which controls one aspect of a particular process - for example, the temperature of an oven.
