Abstract :
In this work, we develop an approach for the control of multi-phase and distributed chemical process systems by considering the physics of a process coupled with inventory control, passivity and thermodynamics. The incidence of these theories allows us to assess the stability of a general, distributed process system and stabilize the performance around given fixed reference points. The theory we develop is applied to a simulated model of an electro-chemical process making Silicon, a pre-cursor material for electronics and silicones. Open and closed loop simulations are prepared and discussed.
