Examination of Electromagnetic Noises and Practical Operations of a PMSM Motor Driven by a DSP and Controlled by Means of Field Oriented Control

摘要

This paper presents main problems of practical implementation of filed oriented control (FOC) dedicated for a permanent magnet synchronous motor (PMSM). By means of this work, elements of FOC's mathematical model and practical implementation of the electronic commutator are presented. It is based on the DSP processing unit IGBT power module. The measurement system consists of control unit equipped with inverter and encoder. The main element of driving system is PMSM drive. There are two main problems addressed in this paper: electromagnetic distortions and proper calculations in real systems. This work is intended to resolve these problems. Described solutions have been implemented and examined practically.
