Abstract : a two - pole axially - laminated anisotropic ( ala ) rotor reluctance motor, with a high saliency ratio, is de - veloped. based on it, the performance characte istics of the motors are investigated with open - loop operation. it is proposed that an intensive oscillation occurs at low speed, corresponding to the frequency supplied a little greater than the natural one of the system
文摘:研製了一臺高凸極比的兩極ala轉子磁阻同步電動機,實驗研究了電機的開環運行特性,研究結果表明電機開環運行時存在一個比較嚴重的低頻振蕩,這個振蕩發生在電機電源頻率略大於電機的自然頻率后的某一頻段,且會導致電機失去同步 -
A scanning system under open loop operation based on the mathematical model is studied and designed, including the identification of hysteresis model parameters and obtaining of the inverse model
本文完成了基於遲滯數學模型的開環控制系統的設計研究,包括遲滯數學模型參數的識別,逆模型的求取。 -
The task in the open loop system is to get lpg injection duty ratio in pre - set two dimension map according to practical engine operation condition, while the task in the closed - loop system is to calculate lpg injection duty ratio by the approaching increment method or the proportion and integral ( pi ) controller according to the signal of the oxygen sensor. to eliminate the oscillation phenomena of the signal of the oxygen sensor in low - speed condition, this paper develops the stable increment method
開環階段根據實時工況參數對事先制取的噴氣占空比map圖執行取值操作;閉環階段根據氧傳感器反饋信號通過增量逼近法或pi環節計算輸出適合即時工況的噴氣占空比值;為解決低速振蕩現象,本文運用固定增量法,對系統進行低速振蕩微調。
