H_∞ Control Theory Using in the Air Pollution Control System

摘要

In recent years, air pollution control has caused great concern. This paper focuses on the primary pollutant SO2 in the atmosphere for analysis and control. Two indicators are introduced, which are the concentration of SO2 in the emissions (PSO2) and the concentration of SO2 in the atmosphere (ASO(2)). If the ASO(2) is higher than the certain threshold, then this shows that the air is polluted. According to the uncertainty of the air pollution control systems model, H-infinity control theory for the air pollution control systems is used in this paper, which can change the PSO2 with the method of improving the level of pollution processing or decreasing the emissions, so that air pollution system can maintain robust stability and the indicators ASO(2) are always operated within the desired target.
