FPGA based real time fuzzy fault detection algorithm

This paper presents a fast fuzzy algorithm, implemented using field-programmable gate array (FPGA) to detect the stator related faults in induction motors. Altera Cyclone III FPGA was employed for developing the proposed method. All coding of fuzzy algorithm was written using hardware description language (HDL) called very high speed integrated circuit description language (VHDL). Fuzzy system has three inputs and one output. The magnitudes of three phase current signals were given to the fuzzy system and stator related faults were detected. The validity of the proposed method was tested by experimental data set and was also compared to the results of MATLAB fuzzy logic toolbox. The experimental results show that the proposed method gives very efficient and reliable results for fault detection of induction motors.
