Compared to traditional power plants, ultra supercritical power plants raise the pressure of the working medium, usually water, in their boilers to improve their generating efficiency. This thesis focuses on the way to improve the bustion process control system of the power plant to reduce the interferences during each of the power plant control variables. So that we can further improve the generating efficiency of our power plant. First of all, according to the working principle of the power plant we analysis how its control variables and controlled variables affect each other, so we can build a mathematical model of them. Secondly, by using PID controllers, decoupling or other ways we set up an improved bustion process control system control plan. Then, by searching the Inter we find some data from a real ultra supercritical power plants in order to input them into our mathematical model. Last of all, through Simulink, a toolbox from MATLAB we make
