This paper advanced a kind of squirrel-cage motor's speed control system adopting a PI controller with on-off control method, accomplished by single-chip computer and adjusting the speed of squirrel-cage motor with changing its voltage.

本文提出一种具有自适应控制效果的交流电动机调速系统。采用继电控制方法自整定和自调整PI调节器，调节交流电动机电源电压调速，单片机实现。

In Chapter II, the structure, parameters and electric single-line graph of RTGs is introduced. The modeling part, as academic base, deduces the running control model, rotate speed control model, motor model and its load characteristics.

本文第二章，对集装箱场地吊结构、参数和电气单线图等进行了说明，作为理论基础，建模部分介绍了场地吊的运行控制模型、转速控制模型和电机模型及负载特性。
