Efficiency Increasing of Traction Electric Drives with Induction Motors and Vector Control System

Compared with traditional three-phase motors, six-phase induction motors due to their high reliabilities and low DC side voltages can achieve high power drives using devices with lower voltage level. In this paper, it analyzes the research status of six-phase induction motors, introduces the winding structures of six-phase induction motors, and finally designs the vector control system for six-phase induction motors taking the Digital Signal Processor (DSP) as the core. It introduces DSP circuit implementations, emphasizes to describe software structures of the control system, and proposes a detailed software flow chart.

Vector Control System

Vector control is one of the most popular control techniques of induction motors. Owing to its simplicity, the indirect vector control gains increasing popularity. This paper proposes a speed sensor-less indirect vector control system of induction motors based on a novel sliding mode control (SMC) speed observer. The observer uses the stator current difference of the estimated value and the actual value to calculate the rotor speed. The simulation results show that the method has a fast response and high accuracy, and it robust to parameter variations.
