Unit Description and General Aims
This subject aims to provide students with an in-depth knowledge of the techniques and technologies employed in the automated control of industrial processes. The subject combines the fundamentals of process identification and feedback control design with a broad understanding of the hardware, system architectures and software techniques widely used to implement control solutions. Students will acquire the ability to analyze control problems and create solutions based on the use of modelling techniques and well-established software tools. This ability will help to prepare the students for the advanced control topics to be covered later in the course.
Students will be able to describe the key features of control system equipment practices and their comparative investment costs as used in different sectors of industry. Control techniques for both continuous and batch process control will be covered, Students will undertake case studies to create and evaluate choices of system architectures and equipment solutions in terms of plant availability, initial cost and potential for improvements in plant performance indicators such as energy efficiency and production rates.
