Abstract :
Due to the large delay, strong nonlinearity and coupling among variables of the rotary kiln production process, we select the roasting material temperature, oxygen content and kiln tail temperature as control objectives of a nickel-iron rotary kiln, then the intelligent sampling and PID control system based on operating conditions identification is designed. At the same time, a ratio controller is designed for the difficulty of coupling for fuel and wind. Last the mathematical model of kiln tail temperature, oxygen content and burning zone temperature is obtained through the Matlab System Identification Toolbox. The rationality and practicability of the automatic control program is verified by dynamic simulation.
