There are usually no on-line product quality measurements in batch and semi-batch processes, which makes process control very difficult. A model was developed to predict end-product quality from available on-line process variables measured early in the batch using the partial least squares method. Some available mid-course quality measurements were used to correct the final prediction results. Since the process may change with time, the model is updated with new batch data to generate new model parameters after each batch. A simulated batch polymerization process demonstrates that the method can accurately predict end-product quality.
