測量(liang)電樞(shu)電壓以確定其變化范圍；（對于一個給定，一般可取40%左(zuo)右大給定）

3、在上述條件(jian)下(xia)測量測速發電機的反饋電壓；

4、在上(shang)述條件下測量電機的電流；

5、人為(wei)增加電機(ji)負載觀察電機(ji)轉速變化(hua)，如果負載增加速度明(ming)(ming)顯(xian)變化(hua)，應將IMAX增大；如果沒有明(ming)(ming)顯(xian)變化(hua)，進入(ru)下一步；

6、調整(zheng)反饋增益（增大(da)或(huo)減小看是否(fou)有變化(hua)）如(ru)果沒有變化(hua)，恢復到調整(zheng)前位置，進入下一(yi)步；

7、調整速度環比例增益(yi)，積(ji)分電(dian)容(rong)，以使速度穩定(ding)；

8、重新整定電流環參數；

9、在全部設定(ding)(ding)范圍試車，進行精調，以(yi)求(qiu)在所(suo)有速度段，負載任何變化下都(dou)保持速度穩定(ding)(ding)；

10、生產試車(che)以確認滿足其工藝(yi)要(yao)求(qiu)。符(fu)合(he)要(yao)求(qiu)完成維修，不符(fu)合(he)，根據需要(yao)調整參數。
