On the use of Macsyma symbolic language to generate simulation softwares for the control of converter-machine drives

The study of the complete electric machine-power converter control association is made easier by splitting the system up into several functional blocks. Different simulation software packages, with a modular approach, exist to study this kind of application. To solve these problems due to the modular approach and to keep this approach for the description of electric machine-power converter control associations, the authors have developed the tool presented in this paper: MGS. It is based on the Macsyma symbolic language, using a modular description for users and automatically generating programs with a global approach. The example of the self-controlled synchronous motor system is used to illustrate this new idea
