摘要
根据异步电机在两相静止αβ坐标系上的数学模型,利用Matlab/SimuLink软件可构造用于仿真的交流电机模型。该模型采用SimuLink中的模块构造。由于矩阵A不是常数矩阵,将矩阵A分解为定常和时变两部分,故此系统是非定常系统。模型的封装,是从模块库中选出需要的模块,根据函数关系进行连接,并将其模块化成为子系统。其创建方式:一是在模型中加入一Subsystem模块,然后加入组成子系统模块;另是将已经连接好的模块集合创建子系统。为检验模型的正确性,将该模型接入90V的对称三相正弦电压,其输出波形符合电机的运行特性。
According to the mathematical model on αβ coordinate system of asynchronous motor, the model of AC motor is established with Matlab/Simulink software. The model consists of Simulink modules. Owing to matrix A is not invariable matrix, matrix A is divided into invariable and variable two parts, so, the system is variable system. Selected module in module library and then packaged them. Connected the modules on the basis of function relation, and composed a subsystem. Its steps are that add subsystem module in model,and then add the modules that compose a subsystem. for the sake of proving accuracy of the model, AC motor was wired in 90Vvoltage with symmetrical triphase sinewave, the output waveform accords running characteristic of the motor.
