Model-Based Predictive Control Method of Batch Process with Integrated Quality Control Function

摘要

The present invention relates to a model-based predictive control method of a batch process incorporating a quality control function, and relates to a model-based predictive control method of a batch process in which a quality control function is incorporated, and a process model function obtained by correlating an input variable, a controlled variable, a quality variable and a disturbance with a linear algebraic equation process; The process model function is used to calculate an output error and an ash in the current pre-ash period based on the reference output trajectory, the total input / output variable of the previous ash, the quality variable of the previous ash, the input / output variable up to the current time of the current ash, Estimating a filtered value of the quality variable control error after the end of operation; By using the process model function and using the estimated values of the reference output locus, the total input / output variable value of the previous pollen, the quality variable of the previous batch, the output error in the estimated current round- A prediction process for predicting an output error after the current time and a quality variable control error after the ash operation as a function of the input value to be supplied after the current time; Calculating an input variable trajectory that minimizes the objective function by making an objective function with an output error prediction value and a final quality variable control error prediction value after the current time of the current batch; And a process control process of operating a target process in accordance with an input variable trajectory that minimizes the objective function, to provide a batch process model based prediction control method incorporating a quality control function
