需要控制的電機及變頻器自身
1)電機的極數。一般電機極數以不多於(極為宜,否則變頻器容量就要適當加大。
2)轉矩特性、臨界轉矩、加速轉矩。在同等電機功率情況下,相對於高過載轉矩模式,變頻器規格可以降額選取。3)電磁兼容性。為減少主電源幹擾,使用時可在中間電路或變頻器輸入電路中增加電抗器,或安裝前置隔離變壓器。一般當電機與變頻器距離超過50m時,應在它們中間串入電抗器、濾波器或採用屏蔽防護電纜

1、控制定子磁鏈引入定子磁鏈觀測器,實現無速度傳感器方式;
2、自動識別(ID)依靠的電機數學模型,對電機參數自動識別;
3、算出實際值對應定子阻抗、互感、磁飽和因素、慣量等算出實際的轉矩、定子磁鏈、轉子速度進行實時控制;
4、實現Band—Band控制按磁鏈和轉矩的Band—Band控制產生PWM信號,對逆變器開關狀態進行控制。
矩陣式交—交變頻具有快速的轉矩響應(<2ms),很高的速度精度(±2%,無PG反饋),高轉矩精度(<+3%);同時還具有較高的起動轉矩及高轉矩精度,尤其在低速時(包括0速度時),可輸出150%∼200%轉矩。
