Blast furnace TRT top pressure control method based on the feedforward mechanism modeling

According to the stability requirements of blast furnace top gas pressure,a model for TRT system is established through analyzing the configuration of TRT system and identifying the system parameter.The angle of stationary guide blades and the opening of bypass valve are used as manipulated variables to control the top gas pressure of blast furnace.Based on the model,a feedforword controller is designed for TRT system in case of emergency.
