Study on Analysis and Simulation of Double Electrical Machinery Transmission System

提出一种通过矢量控制和差频控制原理控制的双电机传动系统。对变频控制异步电动机在不同频率和负载下的运动特性进行仿真研究。还简述Simulink的S-函数的核心内容,针对现代矢量控制系统中异步电动机高阶、非线性、强耦合的特性,推导出其状态方程形式的数学模型,并用S-函数实现。从而实现对本系统的仿真研究。

This paper provides both vector control and frequency difference control to modulate the system of double motors transmission. The voltage frequency relation that asynchronous motor works under the states of different frequency and the characteristics thai it runs with different frequency and different load are researched by simulation.This paper states briefly the content of S- Function. Also has summarized the Simulink S-function core content. Based on features of the asynchronous motor such as higher order, non-linear, the strong coincidence characteristic in view of the modem vector control system, its equation of state form----the mathematical model has been worked out and it is realized by means of the S- function. Thus, this system simulation research has realized.
