摘要
提出了一种通过矢量控制原理和差频控制原理来控制的双电机传动系统。对异步电动机变频控制在不同的频率和负载下的运动特性进行了仿真研究。简述了S im u link的S-函数的核心内容,针对现代矢量控制系统中交流异步电动机高阶、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,从而实现了对本系统的仿真研究。
A kind of double motor drive system controlled by vector control principle and difference frequecy control principle is presented. The simulation research is made for the motion characteristic for the different frequency control of asynchronous motor. Also,the core content of S-function for simulink is sketched. For the high order,nonlinear and strong coulping characteristic of AC asynchronous motor in modern vector control system,develop mathematical model of its equation of state form and achieve by S--function, thus to bring about the simulation research of the system.
