There are five parts are as follows : in part one, the concept of switching function is introduced first to establish the nonlinear mathematical model of the induction motor variable frequency speed adjustment system which is fed by a sine pulse width modulated ( spwm ) inverter and takes the effect of the main magnetic circuit saturation into consideration, then the low frequency oscillation of the system is simulated according to the model. next, from the view point of energy conversion of the inverter - induction system, a criterion for the low frequency oscillation is proposed to determine whether the system is in low frequency oscillation which is judged by whether the interval of the negative current component of the inverter input current is more than 1 / fc ( fc is the carrier wave frequency of the inverter ) or not
首先引入開關函數概念，建立了正弦脈寬調制（ spwm ）逆變器供電異步電動機，考慮主磁路飽和時的變頻調速系統整體數學模型，模擬系統的低頻振蕩；其次從逆變器-異步電動機系統能量轉換角度出發，提出通過檢測逆變器輸入電流中負電流的間隔時間是否大於1 / f _ c （ f _ c為逆變器載波頻率）來判定系統是否出現低頻振蕩；最後的實驗結果驗證了系統低頻振蕩建模和判據的實用性和正確性。“ for a prediction to be successful, the probability of occurrence in a time interval and a space domain must be specified in advance, as must the lower magnitude
「一項預測稱之為成功，發生的概率，包括時間的間隔、位置的范圍，以及最低量級，均必須事先明確。“ for a prediction to be successful, the probability of occurrence in a time interval and a space domain must be specified in advances, as must the lower magnitude
「對於一項預測作為成功的，預測必須事先明確發生的時間概率的間隔偏差以及空間范圍偏差，以及最低的震級。
