8098──磁通轨迹控制PWM模式变频调速

A Magnetic Flux Control PWM Inverter by Micro-8098

本文引入一种新的交流传动控制思想，即采用磁通轨迹控制模式的ＰＷＭ．该控制思想是针对目前人们用得较多的感应电动机传动用逆变器的ＳＰＷＭ法所存在的不足而提出的，通过理论推导给出了实际的控制模型和方案，进而引入目前最新的、具有高性能低价格的８０９８单片机最小系统，对ＧＴＲ变频电源实现微机控制并实现了控制思想的软件化．

This paper presents a new kind of AC electric transmision control method,that is: a control method of the inverter by magnetic flux control PWM. It is directed against the existing disadvantags that people have been generally adopting the SPWM method of the inverter of AC induction motor at present; the magnetic flux control PWM method is narrated; an actul control mode and scheme is concluded from deduction theortically; and then,a 8098 single-chip Microcomputer minimum system is introduced, the PWM pattern generation and the system control of GTR inverter are achieved by software of the 16-bit single-chip Microcomputer.
