Fast Prototyping Of Vector Controllers For Interior Pm Synchronous Motors

This paper proposes a prototyping procedure for interior permanent magnet synchronous motor drives, which allows to speed-up the implementation of the optimal current vector-control strategy tailored for the specific motor design. The “direct” and “quadrature” axes currents optimizing the motor performances are obtained directly by the finite elements analysis at the designing stage, stored in form of mono or bidimensional arrays, and imported in “Matlab/Simulink TM”, where a custom model is developed to simulate both the motor and the drive-controller behavior. Once refined through simulation, the characteristics are processed by a software driver to produce the format readable by the specific real-time digital controller. As an example, the fast prototyping of an IPM motor drive for an electrical city-scooter is presented, using a TMS320F2812 DSP controller.
