| Outline of Final Research Achievements |
In this research project, we aim to develop passivity-based robustness analysis of genetic network systems. The following two problems are mainly addressed and solved: 1) Robust instability analysis for general nonlinear dynamical systems is studied. Then, the proposed analysis theory is applied to qualitative and quantitative robustness analysis of oscillatory behavior appears in genetic networks and cell differentiation and reprogramming. 2) We found the robustness of a class of genetic networks is reinforced via the network scale-expansion. The reinforcement is modeled by the interconnection of strictly-passive dynamical systems. It is further investigated that the essence of the model is applicable for design problems in other research fields such as stabilization of power systems.
