Then, as the substitute of the traditional pi controller, neuron adaptive psd controller is used to alternate the velocity loop of dc driver system, simulation results show that the super - shoot in new system is small and the performance in the way of anti - disturbance and anti - time - varying parameters are higher than the traditional pi controller and robustness of the dc driver system improved greatly, in addition, through analysis of the character of the neuron adaptive psd controller, the paper presents a neural network self - tuning control method for dc driver system in which the diagonal recurrent neural network is used to identify the plant to calculate the plant ' s sensitivity for psd controllers simulation results indicate that excellent static dynamic target was got with this control method and the performance of the system is improved greatly,
然後，應用單神經元自適應psd控制器改造調速系統的轉速環，代替傳統pi調節方式的轉速控制器。模擬表明，新系統在超調、抗負載擾動和參數時變方面性能優于的傳統的pi控制方式，系統的魯棒性增強。在分析單神經元自適應psd控制器特性后，本文提出用對角遞歸神經網路辯識控制對象，為psd控制器提供靈敏度參數，從而構成一神經網路自校正控制方案。 -
After phase 4, inspection and validation, the training center pi should coordinate with the corresponding air carrier pi if applicable, make an evaluation agreement on the training center regulation compliance, and submit this evaluation agreement to the regional administration flight standards office and the principal manager of the regional administration, make the decision of whether to issue the certificate or not, at the same time, apply for the certificate number of ccar - 142 training center to the flight standards department, the two character code of pinyin represent each administration, for example, hd represents east china regional administration, hb represents north china regional administration etc
完成第四階段驗證檢查后，訓練中心主任監察員應當與相關航空承運人主任監察員進行協調如適用，就訓練中心規章符合性問題達成一致意見，並將此意見提交給地區管理局飛行標準處和管理局主管領導，做出是否頒證的決定，同時可以向飛行標準司申請ccar 142部訓練中心合格證代碼，其中漢語拼音的兩字代碼分別表示不同管理局，如hd代表華東管理局hb代表華北管理局等。 -
Based on the analysis and comparison of the peak current - injection mode and average current mode control strategies, the method of designing average current control mode pi regulator is obtained. the digital simulation of the converter has been done with the help of matlab software. the good transient and stable character of the converter is attained while rated load
在分析與比較峰值電流模式與平均值電流模式控制策略的基礎上，給出平均值電流模式pi調節器的設計方法，利用matlab軟體對變換器進行了數字模擬，證實了變換器在額定功率范圍內動、靜態特性良好；過載情況下變換器具有自動限流、保護主功率器件的特性。 -
Pi formation is combination of thick sand body, because the sediment mode of reservoir in changyuan of daqing is mainly combined of great leaf delta and partly fluvial facies, about 500m thick, combined of 130 little sand or mud layers, which is typical heterogeneity reservoir, the reservoir ' s character is greatly distribute, high permeate and serious heterogeneity
Pi油層組是厚油層組合，由於大慶長垣儲層的沉積模式以大型葉狀三角洲及部分河流相為主，總厚度500多米，由130多個小砂層和泥巖交互而成，是一套典型的非均質砂巖儲層，該儲層具有分佈廣、厚度大、滲透率高和層內非均質性嚴重等特點。 -
In this paper, we studied the reservoir character of pi formation in south first - second region, north of saertu
本文研究薩爾圖油田北一二排p1油層組的儲層特性。
