Abstract
The work presents a fault detection method for an induction motor drive system with inverter output filter. This approach make use of a load torque state observer, which complete structure is presented along with the used control structure. Moreover, the demonstrated drive system operates without rotor speed measurement in conjunction with the multiscalar control. The verification of the demonstrated idea was performed on an experimental test setup by introducing drive faults, e.g.: misalignment of the machine and unbalance of the drive shaft. Finally,an FFT analysis of the presented results confirmed the beneficial usability of the developed diagnostic tool.
