| 摘 要： | 在交流调速系统中，调速精度较好的一种是变频调速，但变频调速由于交流机的特点，转矩控制困难，在交流机控制系统中，要想用古典控制理论来综合是不易办到的，所以我们采用变结构恒转差控制，把一个复杂的非线性系统化成一个典型非线性系统，结构简单，用非线性仿真方法进行调节器参数优化选择，经过多次实验效果较好。

| Abstract: | In alternating current velocity modulation systems, the precision of the frequency conversion velocity modulation is adequate, but, because of the characteristic property of the alternating current motor, the rotation moment control is difficult for the freqrency conversion velocity modulation. For this reason, we adopted the structure conversion method to realize constant rotation deviation control. A complicated nonlinear system was converted into a typical nonlinear system. The structure is simplified. The parameters of modulators were selected by means of the method of nonlinear imitation. The result was satisfactory for many experiments. |
