This text book is priceless for those researchers and engineers who are enthusiastic in carrying out research in designing of speed controller of Variable Frequency Induction Motor Drives (VFIMDs) which are the vertebrae of the industrial world. The chapters in the book have considered the various Artificial Intelligence (AI) techniques in order to properly design and tune the speed controller for DFOC and DTC based induction motor drives. The AI based controllers have given improved dynamic response of the two VFIMDs for disturbance rejection capability, robustness and stability under...
