Intelligent Control Algorithm Application In Distributed Control System

This thesis has introduced the structure, disposition, structure and technology characteristic and system software design plan of self-developed LN2000 Distributed Control System. On this basis, the paper introduces relevant things how virtual DCS based on self-developed LN2000 system is developed including DCS technology resources, virtual algorithm base, virtual DPU and simulation function. We demonstrate the process of controlling superheated steam temperature. Virtual DCS redounds to training and application for DCS. And simulation function makes secondary development easy. The thesis details the realization of single neuron self-adaptation control algorithm and expert PID control algorithm in LN2000 DCS. Utilizing the simulation function of virtual DCS, the thesis demonstrates the control process of the two algorithms respectively. The results prove that the two control algorithms have good track performance and robustness.
