Development of an expert system to fault diagnosis of three phase induction motor drive system

Abstract

Power electronic systems are considered as one of the most important components in many applications, such as nuclear reactors, aerospace, military applications and life saving machines. In such applications the system should be high reliable, a knowledge-based expert system was developed to diagnose faults in a three phase induction motor system . A software tool called KAPPA PC 2.1 was used to develop the expert system, the system is modeled in MATLAB SIMULINK and the simulation results at normal and fault conditions was rewritten as a set of if-then rules by which the expert system can discriminate the fault.
