During the last decade, speed sensorless field-oriented control of induction motor has given a particular attention by researchers worldwide and a great number of papers have been published on this issue. In most of them, the authors proposed the speed estimation algorithms based on Kalman filter theory, neural networks and model of reference. In indirect vector control strategy, the accurate k...

Permanent magnet synchronous motor (PMSM) is a special type of electric that has many applications such as in the manufacturing industry robots, self-propelled mechanisms, medical fiel. In this paper, permanent control structure according to field-oriented (FOC) algorithm will be implemented on field-programmable gate array (FPGA) card. Function blocks FOC for example PI controller, space vecto...

This paper presents a new technique of compensation of the effect of variation parameters in the direct field oriented control of induction motor. The proposed method uses an adaptive tuning of the value of synchronous speed to obtain the robustness for the field oriented control. We show that this adaptive tuning allows having robustness for direct field oriented control to changes in rotor re...

The objective of this paper is to apply the Hybrid Efficiency Loss Minimization control scheme [1] into a FOC controlled ACIM motor drive in order to improve the fast on-line loss minimization control through flux control,. The proposed controller combines a Loss Model Controller (LMC) to control the transient states and a Fuzzy Logic Search Control system (FLSC) to control steady states. The L...

Although, Single-Sided Linear Induction Motor (SLIM) utilization has increased in railway applications due to their numerous advantages in comparison to Rotational Induction Motors (RIM), there are some sophistication in their mathematical models and electrical drive. This paper focuses on the problems of SLIM modeling, with assuming end-effect on the basis of Field Oriented Control (FOC) as a ...
