一种新型的转差频率控制设计法

A New Design Method of Slip-controlled Adjustable Speed System

本文在提出一种较为精确的电流型逆变器——感应电动机(CSIM)系统动态模型的基础上,根据对系统动态和整体性能要求设计出系统的控制部分和调节器的参数。最后应用数字仿真的方法对系统进行控制仿真。结果表明:该设计法是合理可行的,系统性能在动态和静态均优于传统的控制系统。

This Paper first presents a more accurate dynamic model of current source inverter motor. On the basis of the model, the control part and controller parameters of slip-controlled adjustable speed system can be easily determined according to the requirements of the dynamic and total performances. Finally the digital simulation for the control system designed is made. The results Prove that the design is reasonable and reliable, the dynamic and total performances of the designed system are superior to the traditional system's.
