Control of physical processes described by partial differential equations

The evolution of many physical phenomena could be described by mathematical models based on a set of partial differential equations (PDE). The advantage of such models is that they make it possible to envisage simultaneously controlling an infinity of dynamics. Controlling and stabilizing the physical processes described by PDE systems requires multidisciplinary study and is one of the most in-depth research in recent decades. There are now many techniques for controlling such systems and it is important to study these approaches in relation to complex processes.

I have studied such topics related to the control and identification of physical systems described by PDE for many years. The following processes have been investigated more specifically.

ConFuNuc: Control of nuclear fusion. Development of theoretical approaches and numerical methods to control the evolution of the safety profile in a nuclear fusion plasma. The following references could be considered:

Prediction of burns injuries caused by laser occurrences. In such a framework the main objective is to quantify the damage on human skin in order to optimize the protections. The following references could be considered:

Optimization of intumescent coatings. Considering accidental fires and the effect of BLEVE (boiling liquid expanding vapor explosion), it is crucial to improve the systems protection. The following reference could be considered:
