| Abstract | This paper presents the Latent Nestling Method (LNM) formalization in hybrid systems. For the proposed LNM, it is necessary to include places of continuous or differential character, allowing the analysis of continuous dynamical variable. This paper is a continuation of our previous papers [7], [23]. Here, the LNM is exploited to analyze the extension to hybrid systems. One of the contributions of this work is a practical application of the LNM in hybrid systems. The case study is the Lubrication and Cooling system of a Wind Turbine Gearbox. The model of the system is built using colored Petri nets formalism and the classic techniques of continuous and hybrid Petri nets. Simulation results are presented to validate some key concepts of the formalization in hybrid systems.\n Note to Practitioners-The LNM in hybrid and complex systems provided in this paper is easy to implement and potentially applicable for fault diagnosis in any complex system. This method is very suitable where many different sensors and signals are considered, regardless of whether its nature is discrete, continuous, or both. In this case, the method is implemented in a subsystem of a wind turbine, showing the advantages and facilities of application. |
