Abstract

Recent trends in variable speed AC motor drives are toward achieving high performance and high efficiency. Speed regulation of a voltage-decoupled induction motor that provides optimal efficiency and quick response is discussed. Although present-day motor drive applications demand robust and faster control techniques, there are only few applications of modern control theory to AC drives. A robust first-order model reference adaptive control (MRAC)-based speed controller whose stability has been proved via Lyapunov´s second method is proposed. Computer application to a 100 hp induction motor shows the capability of the proposed controller by investigating the transient response and robustness of the drive system
