Some research about sensorless control of induction motors in recent years has been introduced in chapter one. in chapter two, a field - oriented control system with current regulator and voltage source inverter ( vsi ) is presented firstly, which is proved in theory that the voltage feed - forward decoupler can be omitted, the good decoupled control properties of flux current and torque current is also validated by experiments with speed - sensor based on f240dsp real system
論文第二章從異步電機的基本數學模型入手，介紹了一種基於轉子磁場定向的帶電流內環控制的電壓型逆變器輸出閉環矢量控制結構，在理論上證明了該模型可省略電壓前饋解耦環節，採用f240dsp晶元構建的帶速度傳感器實驗系統驗證了其定子電流勵磁分量和轉矩分量有良好的解耦控制特性。 -

Traditional direct torque control uses two value torque regulator which makes zero voltage vector work long and make flux shape bad seriously and makes response time long when the speed of induction motor is very low or drops down quickly. in order to solve this problem the thesis puts forward a new way to use three - value torque regulator, when the motor speed is very low or drops down quickly, the contrary voltage vector is used instead of zero voltage vector and the between the stator flux and rotor flux is reduced quickly so that torque is reduced quickly and response time becomes shorter
為此，本論文提出三點式轉矩調節，這樣當電機低速運轉或給定轉速突降時，不是加零電壓矢量，而是加反方向的電壓矢量，使定子磁鏈與轉子磁鏈之間的夾角迅速減小，從而使電磁轉矩也迅速減小，大大減小了調速時間，同時磁鏈值仍然保持基本恆定，輸出比較穩定的電磁轉矩，這在電機制動過程中非常有用。 -
To reduce the high starting current as asynchronous motors start up directly and eliminate the negative influence that brought about by switching of contact when it starts up with reduced - voltage means, two new methods based on power electronics technology for improving the starting characteristics of three - phase induction motor are presented. one is alternative voltage regulator, the other is alternative voltage chopper. the three - phase regulating circuit - asynchronous motors system and the three phase chopper circuit - asynchronous motors system are analyzed and simulated with matlab
為解決上述問題，本文提出一種基於斬波方式的三相交流異步電動機的軟起動新方法，論文對電路的起動特性、功率因數、諧波以及控制策略進行了研究，模擬結果表明這種基於斬波方式的三相交流異步電動機的軟起動方法比基於三相交流調壓的三相交流異步電動機的軟起動方法具優越性。
