摘要
Two time delay compensation techniques, the Smith predictor and the analytical predictor, are used for bottom composition control of a pilot scale methanol‐water distillation column. The closed‐loop performance of the two predictor schemes is compared to that for a proportional‐integral controller in experimental and simulation studies. The predictors resulted in improved control for both set point and feed flow disturbances. Copyright © 1979 American Institute of Chemical Engineers
