FOXBORO B0132WJ國內(nèi)中低壓固態(tài)（晶閘管）電機軟起動器市場的開拓起步于二十世紀九十年代初，經(jīng)過十幾年的努力，電機軟起動技術及其產(chǎn)品已被市場接受并得到了一定程度的普及應用，但此前國產(chǎn)軟起動器產(chǎn)品在技術上的起點較低，這一點在不斷公開發(fā)表的關于電機軟起動器的專業(yè)論文中也反映了出來，例如凡是采用了單片機控制系統(tǒng)的就稱其為智能化軟起動器（其實電機軟起動器的智能化有其特定的含義）,把電機軟起動器控制系統(tǒng)定義為“現(xiàn)代模糊控制系統(tǒng)”等。造成這種局面的原因有以下幾個方面，一是西方發(fā)達國家企業(yè)對外的技術封閉；二是國內(nèi)沒有投入巨額研制費用的企業(yè)和機構(gòu)；三是運用簡單原始的移相觸發(fā)方式就能實現(xiàn)電機軟起動器的原理性運用，使得很多企業(yè)及其技術人員不愿再投入更多的精力和財力，事倍功半地進一步提升產(chǎn)品的各項性能指標。
FOXBORO B0132WJ上海西普信息技術有限公司采用了科學先進地也高新技術產(chǎn)品常用的研制方法，那就是在國際先進產(chǎn)品先進技術的基礎上，學習、借鑒、完善、提高。公司的產(chǎn)品研發(fā)人員通過對多款進口品牌先進產(chǎn)品長期地測試、分析和反復地實驗、論證，得出了一套寶貴地較為科學完整的數(shù)學模型，為實現(xiàn)電機軟起動器的智能化奠定了必要的理論基礎。軟起動器智能化技術是目前國際上的一項先進技術，即使在進口品牌中也僅有少數(shù)產(chǎn)品運用了此項技術，上海西普公司為此進行了長期的資金和技術的準備。
XPR1-SH系列智能化電機軟起動器的推出是國內(nèi)電機軟起動技術的一次飛躍，是國內(nèi)首次實現(xiàn)電機軟起動器產(chǎn)品的真正智能化，也是目前國產(chǎn)品牌中唯一具有完全自主知識產(chǎn)權的智能化電機軟起動器產(chǎn)品。該產(chǎn)品已申請專利和軟件產(chǎn)品著作權，并且擁有多項專有技術。
XPR1-SH/CN 數(shù)字/中文顯示系列軟起動器智能起動技術的原理:
FOXBORO B0132WJ智能化軟起動器采用了自適應的軟起動控制技術。所謂自適應是指根據(jù)實際情況運用專家系統(tǒng)的自動調(diào)整并直接應對，而不是先由微電腦學習記義再判斷處理的初級智能化方式。具體地說，就是先根據(jù)用戶設定的參數(shù)實施起動，在起動過程中不斷地檢測電機狀態(tài)及其參數(shù)實時地調(diào)整控制參數(shù)以確保起動性能達到最優(yōu)，其中最關鍵的就是要保證電機加速的平穩(wěn)，在任何狀態(tài)下都要保證電機速度曲線的平滑連續(xù)并且是單調(diào)上升的，不會出現(xiàn)速度拐點。而非智能化的軟起動器在起動過程中不可避免地出現(xiàn)不同程度的電機及電流的抖動現(xiàn)象，即出現(xiàn)了速度曲線的拐點，甚至發(fā)生共振等嚴重抖動現(xiàn)象，給電網(wǎng)、電機乃至負載機械帶來極大地安全隱患。軟起動智能化控制技術之所以能夠保證電機速度曲線的平穩(wěn)上升是運用了電流、電壓、速度等多參量反饋控制系統(tǒng)，采用類似于（但不同于）變頻調(diào)速器的無速度傳感器矢量控制技術的原理，把被控電機的相對轉(zhuǎn)速作為主要反饋參量，不僅電機的速度變化是可測的，電機是否達到額定轉(zhuǎn)速也是可知的，就是說智能化軟起動技術不同于普通控制方式的另一特點是可準確探測并指示電機起動是否成功、何時完成。
FOXBORO B0132WJ以軟起動器常用的電壓斜坡起動方式為例，用傳統(tǒng)的控制方法來推理，可簡單的認為電機的轉(zhuǎn)速近似地正比于電機上得到的電壓。所以如果能保持施加于電機的電壓線性地增加就能使電機線性加速，普通非智能化的軟起動器就是這樣控制電機的，即以用戶設定的起動時間參數(shù)來計算晶閘管觸發(fā)角的變化率，時間到時即告起動完畢。然而情況并非如此簡單，因為上述推理是在負載穩(wěn)定的理想狀態(tài)下得出的，但在控制電機尤其是帶載電機的情況下，實際效果并不理想。上述推理忽視了兩個重要現(xiàn)象：一是施加于晶閘管的觸發(fā)角并不恒等于晶閘管的導通角，二是按計算施加于電機的電壓并不恒等于電機實際得到的電壓。其實，軟起動器的電壓斜坡起動方式實質(zhì)上是想要得到電機速度斜坡的目的，只要達到了電機速度斜坡的目的，我們并不關心軟起動器輸出的電壓是否是斜坡（線性的），這就是智能化軟起動器區(qū)別于普通非智能化的軟起動器的基本設計思想。
