New method of direct reactive energy and torque control for permanent magnet synchronous motor

Janaszek M.

Vol. 54, nr 3

The new control method for Permanent Magnet Synchronous Motor (PMSM) and Brushless DC Motor (BLDCM) is presentee Balance of power in three-phase permanent magnet synchronous motor is based on conservation of energy law. Space vector theory determine. by instantaneous value of phase quantities is applied in mathematical analysis. It makes possible to estimate instantaneous values of reactiv energy and electromagnetic torque. The presented control method belongs to flux-oriented method; it synchronizes current vector in relatio to stator flux vector. New structure of control system as well as block diagram containing all basic elements and operating modes of specifi blocks are described. Simulation studies and experimental results for two kinds of motors: PMSM and BLDCM were performed based on the SPACE development DS1103 system.
