Embedded motor drive prototype platform for testing control algorithms

Abstract

Rapid prototyping is the typical method used by engineers to develop and test control strategies. The paper presents an Embedded Motor Drive test bench for developing and study energy efficient of motor drives. The prototyping platform system uses Matlab/Simulink and Target Support Package for TI C2000 toolbox. A real-time target controller eZdsp F2812 provided with a power stage inverter represents the hardware components since these can run multiple complex control algorithms. A graphical programming interface with hardware-in-loop design process for testing the algorithms is used. The hardware platform integrates the most recent digital signal processing technology and state-of-the-art design methods. Application performances of electrical drive 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 responses at the high-performance operations are required. Most of the controllers are implemented by field-orientation control mode (FOC) since the method laid the motors at maximum theoretical performances. The PMSM control algorithms are tested in a rapid prototyping approach using Matlab/Simulink and the Real Time Workshop (RTW) toolbox. This low cost prototyping control system can be used as teaching tools in the most graduate-level courses in classical and/or modern control theory.
