| 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. |
| Keywords: | material blending method of calculation linearizing adaptive decoupling control mixing control |
