Adaptability dynamic

Adaptive Dynamics Its anticipation of future states and possibilities, based on internal models (which are often incomplete and/or incorrect), often significantly alters the aggregate behavior of the system of which an agent is part. 

A generalized model of an oscillator, subjected to the influence of external waves is considered. It is shown that the systems of diverse physical background which this model encompasses by their nature should belong to the broader class of kick-excited self-adaptive dynamical systems . 

A class of kick-excited self-adaptive dynamical systems is formed and proposed. The class is characterized by a nonlinear (inhomogeneous) external periodic excitation (as regards the coordinates of the excited system) and is remarkable for the occurrence of the following objective regularities the phenomenon of discrete oscillation excitation in macro-dynamical systems having multiple branch attractors and strong self-adaptive stability. 

A striking example of the so formed class of kick-excited self-adaptive dynamical phenomena and systems is the model of a pendulum influenced by quasi-periodic short-term actions, as considered in papers (Damgov, 2004) - (Damgov and Trenchev, 1999).

Figure 20 Application of the dynamic simplex to the compensation of system-drift. An artificial example is considered here in which the temperature is ramped linearly with time and the simplex aims to compensate for the changes in the reaction temperature by modifying the flow rate accordingly. The plot compares the change in the peak wavelength when the flow rate is held fixed at its initial value of 12 llmin 1 and when it is adapted dynamically by the simplex algorithm. In the former case, the peak wavelength increases steadily with time due to the increasing temperature which increases the growth rate of the particles. In the latter case, the peak wavelength remains fairly close to its initial value of 508 nm.

The control strategy of feeds must ensure the amount of fresh reactants needed by stoichiometry. If the reaction is monomolecular, reactant on feed control may be feasible only if the reactor is large (high conversion). For bimolecular reactions, only one (limiting) reactant could be on flow control. The make-up policy for the other reactant should be adapted dynamically, preferably by feeding in recycle after separation.
