The present Thesis is devoted to the study and application of new methods based on the projection to latent structures to batch processes. The potential economic profit and safety and ecological benefit in the improvement of the modelling, monitoring and control of these processes is widely accepted in both the academic and industrial fields.

The document has been structured in three blocks. Firstly, the related literature is revised and summarized in an introductory part. The principal projection to latent structures methods are presented using a comprehensive common nomenclature. Also, the main contributions in the literature for the modelling, monitoring and control of batch processes are discussed.

In the second block of the document, the general features of batch process data and the basis of the methods based on the projection to latent structures are studied. The study, as the rest of the Thesis, is limited to bilinear modelling approaches. This allows to observe the limitations of these modelling methods when applied to batch processes, some of which are stated here for the first time. In this block, a first theoretical analysis is carried out to investigate the dynamic covariance structures of different modelling approaches. The conclusion of this analysis is that the multi-phase modelling structure has a nice feature which makes it specially attractive for batch process modelling: the flexibility to adjust to the process nature. Multi-phase and single-phase processes, with short or long term dynamics -or even combination of both- can be effectively modelled with the multi-phase structure. The second step in this block of the document is to investigate one of the most widely used strategies to set the parameters of the projection to latent structures methods: cross-validation. New algorithms for cross-validation are proposed and extended to the batch process data case. This step is of vital importance for the development of an automatic modelling algorithm for batch data. This algorithm is presented in the last part of this second block of the Thesis. The algorithm, named Multi-phase algorithm, has been designed together with a set of tools to analyze and handle multi-phase models: the Multi-phase Framework. This framework is a modelling approach which combines the automatic recognition capabilities of the algorithms from the field of Computer Science with the well-founded data analysis from the field of Statistics.

After the study of the modelling of batch processes, several applications where this modelling is necessary are investigated in the last block of the document. The problems addressed are: the off-line and on-line monitoring, the on-line end-quality prediction, the on-line estimation of batch trajectories and the process optimization. All these problems share the common feature that batch processes are difficult to understand and to model. Nonetheless, each of the problems studied presents its particularities, which need to be addressed independently. The contributions in each of the applications go beyond the use of the new modelling approach. In both the off-line and on-line monitoring of batch processes, several improvements in the development of the monitoring system are suggested. In the on-line end-quality prediction and estimation of trajectories, a broad comparison among several modelling approaches is supplied. Finally, a new optimization algorithm, based on the combination of self-tuning extremum seeking and projection to latent structures methods, is proposed.
