Application of Differential Geometry for a High Performance Induction Motor Drive

An attempt has been made in the present work to improve the dynamic and steady state performances of the vector controlled induction motor drive. Concepts of differential geometry has been used for input-output linearization of induction motor drive and to decouple the flux and torque loop. State feedback controller has been designed to obtain desired dynamic and steady state responses. Simulation results show that the performance of the drive system with the designed controller is comparable to that with vector controller and the proposed drive system is more flexible.
