초록

Methods are provided for determining an estimated volumetric ratio of a material to total materials in a mixing vessel. In various embodiments, the methods may comprise: summing a commanded input flowrate of the material and a volumetric disturbance flowrate of the material being fed to the mixing vessel; estimating the output flowrate of the material exiting the mixing vessel; negatively feeding back the estimated output flowrate of the material to obtain an estimated volumetric rate of change of the material in the mixing vessel; and integrating the es...

청구항

What is claimed is: 1. A method of operating a computer control system for a mixing vessel to determine an estimated volumetric ratio of a material to total materials in a mixing vessel, comprising: summing a commanded input flowrate of the material and a volumetric disturbance flowrate of the material being fed to the mixing vessel; estimating the output flowrate of the material exiting the mixing vessel based on the summed commanded input flowrate and the volumetric disturbance flowrate; negatively feeding back the estimated output flowrate of the mat...
