A multiple-microcomputer-based control system with a hierarchical configuration is designed to supervise and control a chemical process for synthesizing gasoline from $CO/H_2$ gas.
Of the hierarchical computer system, the role of one slave computer is to control reaction conditions of the chemical process and the other one is to control the mechanism of an automatic sampling and injection of output product. The host computer is devoted to monitoring two slaves, analyzing output product and communicating with human operator.
The control system is designed for a real chemical plant. To show the validity of the designed control system, some experimental results are presented.
