This paper presents a Genetic Algorithm (GA) based fast speed response controller for poly-phase induction motor drive. Here the proportional and integral gains of PI controller are optimized by GA to achieve quick speed response. An adaptive Recurrent Neural Network (RNN) with Real Time Recurrent Learning (RTRL) algorithm is proposed to estimate rotor flux. An online tuning scheme to update the weight...
In this paper, a robust self-tuning fuzzy speed controller for direct torque control using space vector modulation (SVM) technique is proposed for the high performance drives of induction motor. The design of robust self-tuning fuzzy speed controller greatly affects the performance of Induction Motor (IM) fed with a Voltage Source Inverter (VSI). The performance of the proposed self-tuning Fuzzy PI...
A sensorless induction motor drive fed by 3-level inverter is presented, which combines the principle of indirect torque control, space vector modulation (SVM), speed adaptive flux observer and fuzzy logic controller (FLC). By using SVM, the switching frequency is kept constant and it is easy to solve the problems such as neutral point balance, voltage jump, etc, and more accurate results are obtained...
The non-linear state-feedback input-output linearizing control with tracking controllers for a doubly fed induction motor -DFIM- connected to the grid utility is presented. For this purpose, An appropriate mathematical model of the -DFIM- based on the so-called stator-flux field oriented is detailed. In the rotor circuit, a three-level converter with an algebraic space vector modulation is used. Simulation...
