A fuzzy logic controller to line starting performance synchronous motor for a crane system using vector control

This paper presents the design process of a synchronous motor of crane system using vector control of line starting [1]. the preliminary design is d-q model armature rotor line start synchronous motor with vector control for decreasing a starting current and torque. the design allows the synchronous motor to operate at both starting and synchronous speed. the basic equations for park transformation of the rotor-stator for proposed vector control to synchronous motor are presented [2]. the starting performance of synchronous motor,for example in crane application,requires rapid dynamics and precise regulation; hence the need of direct control is becoming an urgent demand. this type of control providesanindependent vector control of torqueand current,whichis similar to a separatelyexcited synchronous motor and offersa number ofattractivefeatures. synchronous motorhasahighstartingtorquewhileseparately synchronous motorcanoperate abovethebase low speedinthe line starting current [3]. this paper designs study and highlights the effectiveness of the proposed vector control methods for a line starting performance of synchronous motor model parameter,using a fuzzy logic controller methods both simulation and manufacturers measured experimental data. asteady state and transient analysis of the synchronous motor is performed belowand abovebase line starting current. © 2016 penerbit utm press. all rights reserved.
