摘要: 用来描述水泥生料混合系统静态特性的输入输出模型是多变量耦合且非线性的.提出一种可使该系统实现线性化和部分解耦的方案.继而设计了基于线性化解耦模型的自适应控制系统,该系统引入基于改进加权最小二乘法的成分估计器,实现高精度、强鲁棒控制.给出了仿真及实际运行结果,并与常规自适应控制作了对比.

Abstract: In cement production,the input/output model used to describe the static characteristics of the raw material mixing system is nonlinear and coupled with interactive variables.A linearizing and decoupling scheme is provided and made the system linearized and decoupled.It is very significant and convenient for analyzing,designing and implementing the control system.An adaptive decoupling control system is designed based on the improved weighted least-square method,the high accuracy and stronger robustness control is realized,the simulation results and practical operation are provided and a comparison is made with the conventional adaptive control system.

Key words: material blending, method of calculation, linearizing, adaptive decoupling control, mixing control
