- Abstract
Simulated moving bed (SMB) chromatographic separation is a new type of separation technology based on traditional fixed bed adsorption operation and true moving bed (TMB) chromatographic separation technology. In order to optimize the performance of the control system, a predictive control method of SMB chromatographic separation process based on piecewise affine model is proposed. The piecewise affine modeling method was adopted to set up the SMB yield process model. The display model predictive control method is used to reduce the complexity of online operations and improve the speed of the control process. The simulation shows that the actual yield output curve of the target and impurities can fit the set target yield value. Finally, by comparing the prediction control results of the segmented affine yield model and the subspace yield model, the effectiveness of the predictive control method based on piecewise affine model is verified.
