Computer Control with Elliott 803B

Introduction The number of professional engineers who come into contact with digital real-time control is rapidly increasing, and exercises with computer control systems are therefore required for education in control engineering. However, the prices of standard process control computers exceed the budgets of many university laboratories, and the computers available at the computer centres are not equipped for on-line control. On the other hand, the number of input and output channels need not be high for the above purpose, since otherwise the study of the control engineering and process dynamic aspects could be outweighed by the load of programming a complex system. For these reasons and, since it was also known that some general purpose computers could be used for on-line data acquisition", it was decided to undertake the adaptation of the Elliott 803B computer at the Computer Centre of the University of Oulu for closed-loop control of physical process models.
