As argued by Ludwig et al. [2], we assume that the predator population in our model has fast dynamics (the predator population grows much faster than those of the predator), i.e., (rholl r).
This model has fast velocity of convergence since its aim is Pareto optima for problem (9), at the expense of quality of solution; for Max Min SU in a contrary, we derive that its solution is equivalent to the optimization problem (9).
The Fire HD models have faster processors, more RAM, and longer battery life than the existing Fire, as well as a front-facing camera.
Simulation results show the designed controllers both have satisfactory performance over the wide range of reactor operating conditions, while LADRC with model information has faster response, less overshoot, better disturbance rejection ability and robustness.
Similar to the positive feedback model, the negative factor model also has fast adaptability.
The Jasinski model has 7 fast, 2 slow, and 2 superslow (7F, 2S, 2SS) variables.
In our original scaling, the Toporikova model has 2 fast, 2 slow and 1 superslow (2F, 2S, 1SS) variables.
Additionally, the Gateway FHX models feature a rapid 2ms response times and the Gateway FHD model has a fast 5ms response time for viewing high quality moving images.
For the values of the parameters used here, the right-hand sides of the, and equations, respectively, are O(1), O(1) and O, respectively, and so the model has two fast variables and one slow variable when ε ≪ 1. (Note that Jin ≈ 5 at the Hopf bifurcation of interest; see Figure 2).
The model has a fast variable representing the membrane potential, V (mV), and a slow "recovery" current given by the variable u (pA).
