High-speed motor is increasingly used in ultra-high precision machining and high-performance machinery. It necessary to achieve closed-loop control of high-speed order realize control. The high-frequency characteristics have brought great difficulties for its realization performance the hexagonal flux direct torque (DTC) method that can reduce switching frequency power devices researched synchr...

Torque ripple is a defect of switched reluctant motors. DITC (direct instantaneous torque control) harnessed to solve the problem as traditional method, which superior TSF (torque sharing function). In this paper, new controller proposed with modified hysteresis and PWM in DITC. With algorithm, error will be reduced The algorithm effective improve sample 0 status period. based on application ze...

This paper presents a comparative study on the Predictive Direct Torque Control method and the Indirect Space Vector Modulation Direct Torque Control method for a Doubly-Fed Induction Machine (DFIM) which its rotor is fed by an Indirect Matrix Converter (IMC). In Conventional DTC technique, good transient and steady-state performances are achieved but it presents a non constant switching fr...

The Direct Torque Control (DTC) is one of the most effective control and modern methods for high performance AC drives in a wide variety of industrial application and conventional DTC technique uses two constant reference values stator flux and torque ripple. In this paper, two approach intelligent techniques such as fuzzy logic (FL) and Artificial Neural Networks (ANN) used to improving the pe...
