The application of fuzzy control in extractive distillation column

This paper introduce the arithmetic design of fuzzy control based on FPGA and the application of chemical manufacture process control. The method of its implementation and parameter selection are proposed. The experimental result shows that the temperature control performance of this regulatory system following the mode of fuzzy control is better than PID control, especially in the ways of working stability and response speed. The device has low cost, greatly improving the economic efficiency of enterprise. Therefore, it is believed to have a promising prospect of extensive application.
