一、绪论以前的论文(1)—(6)曾指出:感应电动机快速响应的矢量理论虽然很流行,但其在理论上有不完备之点,实用上也有不适之处,矢量控制只限于电流型控制也是其中一点。作者提出了代替矢量控制的磁场加速法,它包括电压型控制,与电流型相比较,它有几个突出的优点。磁场加速法控制的基础,就是在感应电动机的等值电路中,控制它的激磁电流保持一定。电流型控制的等值电路为一网目的电路,暂态项为一项,因此,很容易按照不发生暂态项进行控制,但是,控制上如有误差,必然也要发生激磁电流的暂态过程,其衰减时间常数大,控制响应的滞后大。电压型控制的等值电路为二网目电路,其暂态项有二,要使二个都 I. INTRODUCTION The previous papers (1) - (6) pointed out that although the vector theory of fast response of induction motor is very popular, it has some defects in theory and has practical disadvantages. The vector control is limited to the current Type control is one of them. The authors propose a magnetic field acceleration approach that replaces vector control, which includes voltage-mode control, which has several outstanding advantages over current-mode. The basis of magnetic field acceleration control, that is, in the equivalent circuit of the induction motor, control its excitation current to maintain a certain. Current control equivalent circuit for a network of circuits, a transient term, it is easy to control in accordance with the transient does not occur, but if the control error, must also occur transient excitation current Process, its decay time constant, control response lag large. Voltage-controlled equivalent circuit for the two-mesh circuit, the transient has two, to make both
