A Microcomputer-Controlled Variable Speed System of Induction Motor by Using Sliding Mode Control

本文研究、开发了一套采用滑模控制及8098单片机的异步机调速系统,主回路使用IGBT模块构成电流控制型PWM逆变器,从模型出发引入间接型矢量变换控制,进而设计了滑模控制器并辅以仿真研究。建立了结构简单的实验系统,得到了较高的动静态调速性能。

In this paper,a variable speed system by using sliding mode control and 8098 single-chip microcomputer is developed. IGBT modules and current-controlled PWM inverter are applied to the main circuit. Based on models, vector control is first introduced,then the sliding mode controller is designed, with the help of computer simulation. At last, a simple experiment system is set up, showing the high performance at both dynamic and steady state.
