Design and Analysis of Discrete Event Model Based Fault Diagnosis for a Hybrid System Sobhi Baniardalani ardalani@ec iut ac ir Date of Submission 2011 03 12 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree Ph D Language Farsi Supervisor Javad Askari j askari@cc iut ac ir Ali A Afzalian afzalian@pwut ac ir Advisor Isfahan University of Technology Shahid Abbaspour University of Technology Abstract This thesis concerns with fault diagnosis of Discretely Controlled Continuous Systems DCCS which is a universal class of Hybrid Systems HS In a HS the signals of system states or outputs and the inputs have both quantitative and qualitative values This trouble comes from some restrictions in industrial application of fault diagnosis methods for example the outputs of discrete sensors of the system are qualitatively available Such restriction is the main reason for using discrete event models to solve the fault diagnosis problem In this thesis two main classes of discrete event models stochastic automata SA and timed automata TA are used to describe the HS By the geometric method proposed in the thesis the SA description and the TA description are derived directly from the hybrid automaton description of system To obtain a unified framework a new Dioid Algebra is introduced for modeling and simulation of TA This algebra is Union Plus Algebra and results in a unified linear form for presented algorithms Also fault diagnosis problem is solved by introducing a new consistency notion and by using discrete event observers These observers determine the value of consistency of each faulty mode with observed input output sequences In addition diagnosability of the proposed diagnosers is analyzed at the final part of the thesis The effectiveness of the presented method is shown by simulating the obtained results on some systems such as COSY benchmark problem Especially its effectiveness is shown when uncertainties or disturbances may exist in quantitative model of underlying system or the occurred fault has not been considered in the design process of diagnoser Keywords Fault diagnosis discrete event system consistency measure hybrid system
