Abstract
A comprehensive survey is carried outon the different existing methods of
implementing distributed control systems and the undelying theory IS
studied
A microcomputer based control system IS designed incorporating the
following features:
1- The system is highly reconfigurable. The particular control
algorithm of each individual controller can be changed by
connecting the controller to a portable PC, downloading the new
algorithm, then disconnecting the PC.
2- The control system can be easily connected, if so desired, to a
larger system or host computer that may be used for supervisory
control or DOC purposes.
3- The controllers can be tuned locally or remotely, by a human
operator or a self-tuning algorithm.
4- The controllers are designed in such a way as to facilitate system
maintenance.
5- The hardware involved IS available at the local market at
economic p~ces.
6- The system performance does not degrade abruptly should any
individual connection be broken.
A case study is advanced in which an industrial process (complex enough
to warrant the use of a distributed control system) is controlled by the
above described scheme.
