TLDR
In this article, two different projection operators are found, projecting the state space of a continuous stirred tank reactor (C.S.T.R.) dynamic model on the space of asymptotically invariant states and on the true invariant state for a batch reactor.

Thermodynamics and chemical systems stability: The CSTR case study revisited

Audrey Favache, +1 more
- 01 Mar 2009 - 
TL;DR: In this article, the stability analysis of the Continuous Stirred Tank Reactor (CSTR) model by considering thermodynamics-based arguments is considered, and different Lyapunov function candidates related to the thermodynamics, more specifically based on the entropy, the entropy production and the internal energy, are considered.

On the use of extensive variables in process dynamics and control

Christos Georgakis, +1 more
- 01 Jan 1986 - 
TL;DR: In this paper, a novel approach is presented for the physical interpretation of the slow and fast modes of process dynamics and the synthesis of multivariable and nonlinear control structures by the use of extensive thermodynamic variables.

Dynamical modelling, analysis, monitoring and control design for nonlinear bioprocesses

Denis Dochain, +1 more
- 01 Jan 1997 - 
TL;DR: A key feature of the paper is to show how to incorporate the well-known knowledge about the dynamics of biochemical processes in monitoring and control algorithms capable of dealing with the process uncertainty by introducing, for instance in the control algorithms, an adaptation scheme.

Variant and invariant states for chemical reaction systems

Diogo Rodrigues, +3 more
- 02 Feb 2015 - 
TL;DR: A linear transformation is proposed that allows viewing a complex nonlinear chemical reaction system via decoupled dynamic variables, each one associated with a particular phenomenon such as a single chemical reaction, a specific mass transfer or heat transfer.

Response modes of continuous stirred tank reactors

O.A. Asbjørnsen, +1 more
- 01 Nov 1970 - 
TL;DR: In this paper, it was shown that the fundamental stoichiometric constraints on a set of chemical reactions carry over to the dynamics of open systems in the analysis of asymptomatic stability.

Reaction invariants in the control of continuous chemical reactors

O.A. Asbjørnsen
- 01 Apr 1972 - 
TL;DR: In this paper, it was shown that a subset of the thermodynamic states remains invariant to both the chemical reactions and the control actions, and that the reduced reaction matrix and the mean residence time still determine the response modes entirely.
