定性的システム同定法の提案 : (2)制約規則の推定

抄録

This paper and another paper [安部93] propose a method to identify Dynamical Systems qualitatively according to qualitative descriptions about a behavior of observed system. Proposed method performs the following two steps. (1) Identification of Qualitative States. (2) Identification of Qualitative Differencial Equations. This paper is focussed on the step (2). Qualitative States must satisfy several constraints. Such constraints describe a temporal causal structure of observed system and called "Qualitative Differential Equations". This paper proposes a method to identify Qualitative Differential Equations which describe observed Dynamical System. This method becomes possible by identifying relations between Qualitative Values and Qualitative Derivatives according to Qualitative States derived by the step (1).
