Abstract: Induction motors are the dominant components in industrial processes involving electromechanical energy conversion. Safety, reliability and efficiency are major concerns in modern induction motor applications. Since detecting faults on time could avoid costly unscheduled shutdowns, in recent years there has been an increased interest in induction motor fault detection and diagnosis. I...

The current paper presents a Sliding Mode Controller (SMC) for indirect field-oriented Cascaded Doubly Fed Induction Generator (CDFIG) powered through Matrix Converter (MC). proposed SMC employs continuous control strategy to accomplish free chattering fractional-order sliding-mode and ensure that the of first DFIG stator's reactive active power is separated. An MC used provided second stator C...

This paper proposes a new sliding mode control (SMC)  based model reference adaptive system (MRAS) for sensorless indirect field oriented control (IFOC) of a single-sided linear induction motor (SLIM). The operation of MRAS speed estimators dramatically depends on adaptation mechanism. Fixed-gain PI controller is conventionally used for this purpose which may fail to estimate the speed correctl...

 Abstract— A sliding-mode observer for the rotor flux and speed of an induction motor is presented in this paper. It is also proposed another observer that is a modification of the original one to reduce the errors and improve the obtained speed results. The observer is used in a sensorless Indirect Field Oriented Control (IFOC). The original and modified observers are executed in an experimen...

Indirect Field Oriented Control (IFOC) is known to produce high performance in induction Motor (IM) drives by decoupling rotor flux and torque producing current components of stator current. The decoupling control between the rotor flux and the torque is no longer achieved in terms of stator current components this paper introduces a decoupled rotor flux and torque control based on the magnetiz...

Abstract: This paper proposes the discrete dynamic sliding surface control to guarantee the existence of discrete sliding mode and reduce the chattering phenomena for speed control of induction machine drive. In discrete systems, the controller does not control the system during the sampling interval. The great chattering and large control signal are caused by the high switching gain. In this p...
