“…Control system mainly consists of FADEC, HMS and EHMS. It will enable the engine to deliver power, control the engine, and carry out diagnostic and prognostic (Gomezt June 2000), perform engine maintenance through IVHM functionality and other support activities like cooling, relight etc. Various actors are directly associated with its successful executions.…”

An approach to upgrade existing control system and lean architecture principle is presented to optimize the system along with reduction of weight by understanding the physical system design, Engine Health Monitoring (EHM) system and data study from Integrated Vehicle Health Monitoring (IVHM) system (Aaseng n.d.). This paper brings out the integration of EHM sufficiency with IVHM system. Research effort to describe the hardware, software, algorithms and engine parameters required to monitor various events capturing, health and life management issues with IVHM. Here basic functionality will be performance monitoring, vibration monitoring, event monitoring (including stall, surge, over speed, flameout, over temperature, oil parameter and life monitoring) anti ice system with IVHM requirement of mission completion, safety and data protection. A systematic SE approach and methodology with need and requirement is generated using DOORS software (INCOSE 2011). Full requirement capture with engine designer and aircraft designer (Harinarayana, Developing light combat aircraft: foresight as the guiding principle 2004) for integrating with IVHM (Philip A. Scandura October 30, 2005)has been studied and brought out to model the concept using Rhapsody software. Here various operational scenarios has been attempted to make the functional model. Functional model has been tested for various operational issues and a final configuration has been proposed to the designer (Jaw, Van and Mink 7 – 10 May 2007). This study has brought out a perspective work model for a designer and as a result of this the final product will be tested for integrating the EHM with IVHM

“…Of the various methodologies to extract and use the relevant information, the most notable model based techniques are: (a) parity equation [1][2][3]; (b) state estimation [4]; (c) parameter estimation [5,6]; (d) principal component analysis [7,8]; (e) parametric statistical approach [9][10][11][12][13]; (f) neural network approach [14]; and (g) support vector machine [15]. In the model-free case, however, the FDI is usually carried out by performing certain operations on the system variables.…”

Because the magnitude of each order of oscillation signals in the yaw and roll channels of missile control systems varies with various influences, it is impossible to diagnose faults in the sensors of these channels using model-based fault diagnosis. Based on the characteristics of the systems, a method of fault diagnosis with adjacent wavelet coefficient algorithm is given. Further, based on the difference between the characteristics of the Mallat wavelet coefficients and that of Coilflets wavelet, different algorithms are given. Then, thresholds can be properly selected and abrupt faults diagnosed. A method to diagnose disconnection or short circuit faults is also proposed according to the zone of the current and the zone of voltage when the fault occurs gradually. The combination of these two methods effectively solves fault diagnosis problems of sensors in missile control systems.

“…do not appear specifically on it. For example, some authors, like Gomez et al (2000) in [115] or Ganguli et al (2004) in [98], used parametric estimation approaches combined with likelihood tests and least squares, respectively, to identify and isolate several potential failures in gas turbine engines. This approach has been recently overcome by more advanced and powerful techniques in terms of effectiveness, accuracy, robustness, and in economy of computational resources, when dealing with nonlinear models and decoupling the different fault modes.…”

If I had to choose only one person to thank for the support received during the preparation of this document, I would be committing a great injustice, since my path has been enlightened by different estimated collaborators. Nevertheless, I truly have a debt of gratitude with:Dr. Luis Sánchez de León, my dear colleague, because without his unwavering support, his natural born intellectual brilliance, and his complete dedication during these past long years of preparation, even under extremely difficult personal circumstances that still impress me, this work would not have been possible.Dr. José Manuel Vega, master, mentor, and top-class researcher, who provided an enormous support, with his expertise, mindset, generosity, and advice during the sometimes difficult, but still rewarding, elaboration of this thesis. He showed to me the way to follow, he took me under his wings during difficult moments, being a personal and academic reference, while sharing selflessly, even after extremely worrying health circumstances, his vast knowledge regarding the different topics treated in this document.Other brilliant colleagues at ETSIAE-UPM, like Dr. Ángel Velázquez and Dr. Francisco Sastre, have also contributed remarkably to the development of the proposed research line by showing innovative ways to improve results. They provided an unvaluable support during critical moments.And last, but not least, I must thank to the director of this thesis, Dr. José Luis Montañés, master, mentor, and friend since many years, his leading and focused technical approach, his clarity, his passion on everything he endeavors, his smart vision, his continuous support by being always accessible and the pilar upon everything was elevated, and the faith he inexplicably always had in me. I wish I could deserve one day just a fraction of it. He gave me the tools to achieve all the goals I had so far in my life, and he transmitted to me the respect and consideration for the Engineering, the Science, and for our Alma Mater.They are the model or, better said, the mirror in which I wish to contemplate myself in the future. As an engineer, and as a person.Climbing on their shoulders, I could see beyond.
