The dynamic representation of AC drive systems by complex signal flow graphs

Induction motors represent nonlinear higher-order dynamic systems of considerable complexity. They are well amenable to a formal mathematical analysis. It has proved more difficult, however, to comprehend and penetrate in an imaginative way the principles of their operation under transient conditions. Complex graphic signal flow graphs are suited to visualize the dynamic performance of AC machines. They can assist to form an understanding of the internal dynamic processes of a machine and their interactions with external controls.<<ETX>>
