摘要:因为异步电机的物理模型是一个高阶、非线性、强耦合的多变量系统,需要用一组非线性方程来描述,控制起来极不方便。矢量控制的交流变频调速系统具有非常好的性能和效率,在许多要求高性能和高精度的场合,矢量控制体现出来了它巨大的优势。对于电气传动系统的研究,往往会遇到数学物理计算的难题,难于得到比较贴近实际的系统模型,随着计算机的飞速发展,建立比较理想的模型成为可能。7047

Induction motor vector control system simulation
Abstract:Because the physical model of induction motor is a high-level, non-linear, strong coupling multivariable systems, need a set of nonlinear equations to describe, control them extremely inconvenient.Vector Control of AC variable speed system has a very good performance and efficiency in many occasions that require high performance and high precision, vector control manifested its huge advantage. For electrical transmission system of research, often encounter the problem of mathematical physics calculations, it is difficult to get relatively close to the actual system model, along with the rapid development of computer, establish a more ideal model possible.
In this paper, vector control of induction motor based on the principle, by the coordinate transformation and the rotor flux position calculation using Matlab / Simulink to build an asynchronous motor vector control system model. The simulation model is verified not only the correctness, but also for the actual speed control system algorithm provides a reliable basis for analysis.
