Abstract:

Considering that it is difficult to analyze the convergence of iterative learning optimal control for quality control of batch processes, a novel iterative learning control based on data-driven neural fuzzy model for product quality control in batch process was proposed.In the presented algorithm, the region of the searching space for optimal solution is changed by adding a new constraint condition, which resulted in the convergence of the product quality in batch axes.Moreover, the rigorous proof was given.Lastly, to verify the efficiency of the proposed algorithm, it was applied to a benchmark batch process.The simulation results showed that the proposed method was better and could be applied to practical processes, thus it provides a new way for the control of batch processes.
