FUZZY SELFSETTING PID AND IT’S APPLICATION IN COAL MILL CONTROL SYSTEM

Directing against the nonlinear, large time delay, and model timevarying characteristics of coal mill system, a fuzzy selfsetting proportionalintegraldifferential (PID) control strategy has been put forward. Using MATLAB language programming and combining with SIMULINK, the design, analysis, and simulation of this kind controller have been realized. Simulation results show that the coal mill control system designed by using the abovementioned strategy to have more excellent control performance than that designed by using common PID control system.
