针对链篦机-回转窑温度场具有多变量、纯滞后、非线性和强耦合等特点,本文分析研究了链篦机-回转窑温度场中的耦合因素,结合现场PLC控制提出了模糊解耦控制方法,并在Microsoft Visual Basic6.0软件开发平台上设计了模糊解耦控制器。实际应用效果表明,模糊解耦控制算法可以提高温度场的控制精度。
Aiming at the characteristics of grate-kiln temperature field such as multivariable, pure lag, nonlinearity and strong coupling, this paper analyzes the coupling factors in the temperature field of grate-rotary kiln, and proposes fuzzy decoupling Control method, and design a fuzzy decoupling controller on Microsoft Visual Basic6.0 software development platform. Practical results show that the fuzzy decoupling control algorithm can improve the control accuracy of the temperature field.
