也看不懂，不是那專業(yè)，不過英語稍微修改了一下，具體的專業(yè)詞匯還是得你自己把握。
To achieve magnetic field orientation and high performance of torque control, PMSM driving system need to obtain real-time rotor position to control the stator current.
Position sensor is the key sensor, which is indispensable in this system. The high performance of PMSM driving system can be affected by the intermittent sensor fault and complete sensor failure. Therefore, it is urgent and necessary to carry out fault-tolerant control research on position sensor of PMSM vector control system.
Firstly, PMSM mathematical model and vector control theory are introduced briefly. This thesis provides direct scaling method and achieves sensorless operation in the middle and high speed. Based on maximum likelihood algorithm, fault-tolerant control strategy of position sensor failure is proposed for PMSM driving system. Then a novel PMSM driving system with vector control and position sensor fault-tolerant control is presented. At last, SIMULINK model of the system is set up. And it is studied with fault-tolerant control performance through simulation. |
