Combining the principles of variable structure, direct torque control, and space vector modulation for induction motor fed by matrix converter |
|---|
| W. JING-XIN and J. JIAN-GUO |
| This paper presents a novel direct torque control method for an induction motor fed by a matrix converter using the variable-structure sliding mode scheme with the reaching law, in which combined with the space-vector pulse width modulation to ensure a high-performance operation, both in steady state and under transient conditions. The novel variable-structure controllers are designed to provide the fast and accurate torque and flux control which replace the traditional hysteresis comparators. Some experimental results are shown to prove the accuracy and low-ripple operation of the proposed algorithm. |
