Process control systems design

The detailed design and specification of the automatic control schemes for a large project is usually done by specialists. The basic theory underlying the design and specification of automatic control systems is covered in several texts Coughanowr (1991), Shinskey (1984) (1996) and Perry et al. (1997). The books by Murrill (1988) and Shinskey (1996) cover many of the more practical aspects of process control system design, and are recommended. 

The 6ize of the field, its geographic location, and the tight line transportation system provide some challenging operational and control problems. These problems are identified showing how automation has been used to solve then. This includes the use of an integrated supervisory control system and a distributed process control system designed to meet the control needs of future production facilities as the field proceeds to ultimate development.

When a process becomes upset, not just off-specification, but in danger of a fire, explosion, or chemical release, there are process control systems designed to handle the upset.

Another difference between Basic Process Control System design and Safety Instrumented System design is that per ANSl/lSA-84.00.01-2004 (lEC 61511 Mod) these systems are designed and implemented to meet different risk reduction requirements presented by the various hazards. (Chapter 1)... 

Prior to joining exida, Harry was a Control Systems Advisor for Bayer Inc. in Sarnia, Ontario, Canada, where he was also the Supervisor of the Central Engineering Group responsible for process control systems design and maintenance. 

A process control system designed on the assumption that unrealistic conditions can be fulfilled will be only of limited viability, and the money spent on it will yield a poor return. 

Task complexity—The complexity of the tasks being performed has a direct bearing on the level of workload that human operators experience. It is critical that process control system design considers the human operator s competencies and capabilities for performing control tasks. Automation is typically used to remove high-complexity tasks from the human operator s responsibility.

In today s simulation-rich environment, the right combination of hardware and software is available to implement a hands-on approach to process control system design. Engineers and students alike are now able to experiment on virtual plants that capture the important non-idealities of the real world, and readily test even the most outlandish of control structures without resorting to non-intuitive mathematics or to placing real plants at risk.
