Résumé : Scientific framework and project objective: This project fits into the objectives of the laboratory LAGEP at the interface of chemical engineering and control process. The objective of the new team is the robust control law synthesis for distributed parameter systems with their implementation on the PSA (Pressure swing adsorption) lab process. The challenge is to associate new theoretical results with their implementation on a process. H infinity control by spectral factorization, quadratic linear control and spatial discretization methods will be tackled in this project. In parallel, the experimental setup will be entirely instrumented in vu of testing the produced control laws. The creation and the diffusion to the community of a benchmark associated with this problem will permit a fruitful use of the experimental plateform.   Project synopsis and methods: The pressure swing adsorption pilot process is a cyclic process made up of two columns filled with zeolite. The separation is based on the fact that one of the components is preferentially adsorbed in the surface of zeolite. This adsorption occurs at high pressure. Desorption takes place at low pressure. Several models with different degree of accuracy are already proposed and a control strategy based on optimal control is under study. The objective is to use the adjusted models and to develop new control laws and methods. This will be done for distributed parameter systems with their associated techniques. Several approaches will be investigated and compared: first classical approaches for control of distributed parameter systems and for boundary control system will be performed. Moreover H infinity techniques and quadratic linear ones by spectral factorization will be proposed. Numerical aspects related to the implementation of these control laws will be studied. We will focus in particular on the effect of the discretization method of the control law on the closed loop performance. The objective will be to take into account this approximation in the control law synthesis.   Expected Results: They are numerous:   1. Obtaining of a models base for the pressure swing process: knowledge model for validation, port based models (thermodynamical consistent models), lumped models,...  2. Adjustment of robust control law for distributed parameter systems (H infinity control and LQ control by spectral factorization, passivity). Study of the influence of the discretization method during implementing. Taking into consideration of the discretization in the control synthesis.  3. Complete instrumentation of the PSA pilot process of LAGEP, development of an experimental platform for control of distributed parameter systems, open to other research teams and creation of a Benchmark for these systems.
