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。

三相全控橋式整流電路。使用軟啟動器啟動電動機時,晶閘管的輸出電壓逐漸增加,電動機逐漸加速,直到晶閘管全導通,電動機工作在額定電壓的機械特性上,實現平滑啟動,降低啟動電流,避免啟動過流跳閘。待電機達到額定轉速時,啟動過程結束,軟啟動器自動用旁路接觸器取代已完成任務的晶閘管,為電動機正常運轉提供額 定電壓,以降低晶閘管的熱損耗,延長軟啟動器的使用壽命,提高其工作效率,又使電網避免了諧波污染。軟啟動器同時還提供軟停車功能,軟停車與軟啟動過程相反,電壓逐漸降低,轉速逐漸下降到零,避免自由停車引起的轉矩衝擊。
