Development of Adaptive Speed Observers for Induction Machine System Stabilization

Ahmed A. Zaki Diab, "Development of Adaptive Speed Observers for Induction Machine System Stabilization "
English | ISBN: 9811522979 | 2020 | 80 pages | EPUB, PDF | 13 MB + 4 MB

This book describes the development of an adaptive state observer using a mathematical model to achieve high performance for sensorless induction motor drives. This involves first deriving an expression for a modified gain rotor flux observer with a parameter adaptive scheme to estimate the motor speed accurately and improve the stability and performance of sensorless vector-controlled induction motor drives. This scheme is then applied to the controls of a photovoltaic-motor water-pumping system, which results in improved dynamic performance under different operating conditions. The book also presents a robust speed controller design for a sensorless vector-controlled induction motor drive system based on H∞ theory, which overcomes the problems of the classical controller.
