| 摘 要： | 提出了一种变频调速系统的设计方法，探讨了工程设计法在异步电动机变频调速系统中的应用。在建立异步电动机和变频器数学模型的基础上，按照工程设计法设计出PI调节器，并进行了双闭环控制实验。实验结果表明通过双闭环控制，改善了系统的动态性能和静态性能，扩大了调速范围，提高了调速的精度。

| Abstract: | A designing method on inverter-speed governing is studied, and the application of engineering designing method in this system is discussed. On the base of ma thematic model of induction motor and inverter, engineering designing method is used to design the PI regulator, and experiments on the double-closed-loops system is carried out. Experiments show the static and dynamic capability of the system and the accuracy of speed control are improved. |
