Abstract :
Considering that main steam pressure of combustion system is a big-lagged, big-inertial and nonlinear object, the furnace radiation signals can rapidly reflect changes in combustion rate. A new controller based on the H∞ mixed sensitivity is applied as outer loop. By choosing proper weighting function, the MATLAB robust toolbox is used to obtain the H∞ optimal controller. Simulation result shows the project is effective to control nonlinear and big-lagged system.
