|Abstract:||Permanent Magnet Synchronous Motors (PMSM) have wide applications in industry, especially in AC servo drives.Digital Signal Processors (DSP) has greatly enhanced the potential of PMSM servo drive in such applications. Most of controller drives the PMSM by using the field orientation control mode. This method laid the motor at maximum theoretical performance.This paper presents the field orientedvector control scheme for permanent magnet synchronous motor (PMSM) drives, where current controller followed by hysteresis comparator is used. The field oriented vector control, that regulates the speed of the PMSM, is provided by a quadrature axis current command developed by the speed controller. The simulation includes all realistic components of the system. This enables the calculation of currents and voltages in different parts of the voltage source inverter (VSI) and motor under transient and steady state conditions. Implementation has been done in MATLAB/Simulink. A study of hysteresis control scheme associated with current controllers has been made. Experimental results of the PMSM control using TMS320F24X DSP board are presented. The speed of the PMSM is successfully controlled in the constant torque region. Experimental results show that the PMSM exhibits improved speed stability especially in very low speed range. The validity and usefulness of the proposed control scheme are verified through simulation and experimental results.|
