| dc.description.abstract | Magnetic saturation in electrical machines has major influence on operational characteristics of the machine. To apply precise control mechanism on an induction machine, the development of accurate and reliable knowledge of parameter variation in induction machineās operating region during magnetic saturation is needed. This thesis deals with bringing an alternative approach on investigation of the impact of magnetic saturation, on the steady-state operation of the controlled induction motor, using CompactRIO (a powerful control and acquisition system introduced by national instrument). The reason behind the selection of CompactRIO is because it is a rugged, reconfigurable embedded system that can be used for reliable stand-alone control applications. Control engineers can be benefited from FPGA technology without any knowledge of hardware description language, because CompactRIO can be developed using LabVIEW development platform. The core essence of the presented work is to obtain required steady-state torque with minimal stator current. The influence of the mutual inductance mismatch (difference between the value of parameter Lm used in the controller and the real value of Lm in the machine) due to saturation is analytically verified in a simple mathematical-model modification that reduces the influence on the drive performance. Methods for the selection of magnetizing reference current are provided and effectiveness and accuracy of this investigation method is verified by LabVIEW simulation. | en_US |
