【正文】 continuous amount at the interval [%, +%], based on the equations as follows, There is a decision forms of the fuzzy logic algorithm based on the above principles, which was stored in the programme storage cell of the controller. While the difference of the distribution of the loads between the two Switched Reluctance motors could be got, the duty ratio of PWM signal of the Switched Reluctance motor 2 will be regulated based on the decision forms of the fuzzy logic algorithm and the distribution of the loads between the two Switched Reluctance motors could be balanced. IV. TESTED RESULTS The developed double Switched Reluctance motors parallel drive system prototype had been tested experimentally. Table I gives the tests results, where σ is the relative deviation of the average DC supplied current of the power converter in the Switched Reluctance motor 1, σ is the relative deviation of the average DC2 supplied current of the power converter in the Switched Reluctance motor 2, and, TABLE I. TESTS RESULTS OF PROTOTYPE It is shown that the relative deviation of the average DC supplied current of the power converter in the Switched Reluctance motor 1 and in the Switched Reluctance motor 2 is within 177。另一方面，為了節(jié)約開采成本，巷道空間是有限，以至于設備很難維護。但是，礦井中電機傳動系統的散熱性差，是因為為了煤礦安全，電機傳動系統被封裝在防爆的外殼內。因為不需要冷卻轉子，所以很容易冷卻電動機。 圖一 ： 三相 12/8結構的開關磁阻電動機 功率變換器是由兩個三相不對稱橋式變換器并列組成。比較給定的轉子速度和實際的轉子速度， PWM的占空比調節(jié)如下： 其中， 是給定的轉子速度， 是實際的轉子速度， 是轉 子速度的差。輸出控制參數是開關磁阻電動機 2 PWM信號占空比的增量。模糊邏輯算法是存儲在控制器的程序存儲單元內。 REFERENCES [1] H.
