本文运用Rosenbrock’s多变量现代频域理论研究了电流源逆变器供电的感应电动机变频调速系统,实现了此系统的多变量频域法CAD。设计并研制出简单有效的解耦控制系统。分析和实验证明,此系统物理概念明确,性能良好,可与直流调速系统相媲美。
In this paper, Rosenbrock’s multivariable modern frequency domain theory is applied to study the variable frequency speed control system of induction motor fed by current source inverter, and the multivariable frequency domain method CAD of this system is realized. Design and develop a simple and effective decoupling control system. Analysis and experiments show that the physical concept of this system is clear, good performance, comparable with the DC speed control system.
