Abstract

As to the multi-variable, strong coupling, nonlinear, time-varying characteristics of the ball mill pulverizing system of power plant, a hierarchical fuzzy-PID control system is introduced in this paper based on the fuzzy control theory and the analysis of its dynamic characteristic, and the simulation results are also presented in this article. The simulation results show that the control method of this paper has better quality than the traditional control method, it has fast tracking ability, strong robustness, good decoupling ability, and it can effectively solve the time-varying problem, coupling problem etc.
