Developing embedded control system platform for testing PMSM drives

Abstract

The paper presents an Embedded Motor Drive Prototyping test bench for developing and study energy efficient of the motor drives. The development platform uses an eZdsp target controller with power stage converter that employs Targeted Code Generation from Matlab-Simulink and the Target Support Package for the TI C2000 microcontrollers. Computer Aided Control System Design (CACSD) tools are used to generate real-time code automatically. The reason is to simplify the programming process by making it more graphical and thus more intuitive. Application performances of the electrical drives require energy efficiency, flexibility, outstanding reliability and robust control. Servo drives with Permanent Magnet Synchronous Motors (PMSM) have wide industrial applications where the speed and torque response with high-performance operations are required. The controller drives are implemented by field-orientation control mode (FOC) since the method laid the motors at maximum theoretical performances. A graphical programming interface with hardware-in-loop design processes is used for testing the algorithms controller. The performances are tested in a rapid prototyping approach using Matlab/Simulink and the Real Time Workshop (RTW) toolbox and represent a solution for educational purposes.
