Qualitative modelling and simulations by piecewise linear analysis. En IFAC: Symposium on Artificial Intelligence in Real Time Control (147-152), Delft, Países Bajos: IFAC Proceedings Volumes.1474-6670https://hdl.handle.net/11441/141748Since applications of expert systems were typical in domains with no well defined models, qualitative methods for modelling and reasoning were soon developed. Most current qualitative reasoning programs derive the qualitative behaviour of a system by simulating a hand-crafted qualitative version of the differential equation that caracterizes the model of a system. This paper describes a method to construct a family of piecewise linear dynamical systems from the qualitative information contained in a model. We apply the dynamical system theory to deduce results about the behaviour of the family of dynamical systems constructed as a consequence of the qualitative model.application/pdf6engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Artificial intelligenceQualitative modellingNonlinear systemsinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1016/S1474-6670(17)50813-7
