VECTOR CONTROL OF PERMANENT MAGNET SYNCHRONOUS MACHINE

Abstract

The permanent magnet synchronous machine is a rotating electrical machine with a classic 3-phase stator like that of an induction machine, but rotor is diffe­rent and has surface-mounted permanent magnet. The performance of permanent magnet synchronous machine has improved rapidly by the progress in electro­magnetic material technology. Now permanent magnet synchro­nous machine is widely used because it has many advan­tages such as robustness against the enviroment, high efficiency, light weight and small size. Because of advan­tages above, especially those featuring high effici­ency, permanent magnet synchronous machine is frequently used in industry and is a key equipment in renewable energy applications. In this paper mathematical model of permanent magnet synchronous machine is shown, methods for parameter measurements and the concept of vector control are described. At the end a simulation model of permanent magnet synchronous machine made in Matlab/Simulink program is given.
