The control system of concrete based on decoupling can be able to simplify the actual industrial process. The two elements, the amount of pure raw materials and water content, affect the concretes quality of quick-drying and strength. In this control system, the amount of pure raw materials and water content as inputs, quick-drying and strength of the concrete as outputs, we should consider the coupling between variables. Be possible to achieve the control requirements of the system, we use a diagonal matrix decoupling method to decouple the control system. This paper has described a design method of concrete control based on decouple, established the MATLAB simulation model on the PI regulator system of the controlled object, took the system identification, stability analysis, election of control strategy and parameter tuning, and tried to simplify decoupling regulator. In the end, we took a simulation of system, and an analysis of the robustness. Conclusion is that no coupling systems and coupling system after decoupling have the same simulation results, and has strength robustness.
