Frequency Control System Analysis and Research

交流调速的发展可归纳为三个方面:转差频率控制、矢量变换控制和直接转矩控制等新的交流调速理论的诞生,使交流调速有了新的理论基础;GTR、MOSFET、IGBT等新一代的高开关频率、大功率容量电力电子器件的出现,为交流调速装置奠定了物质基础;微处理器的飞速发展,使交流调速系统许多复杂的控制算法和控制方式得到完善。

AC variable speed development can be summarized into three areas： slip frequency control, vector control and direct torque control of AC variable speed new theory of the birth, so that communication speed with the new theoretical basis; GTR, MOSFET, IGBT, a new generation of high switching frequency, high power capacity of the emergence of power electronic devices, control devices for the exchange laid the material foundation; the rapid development of the microprocessor, the communication speed control system of many complex control algorithms and control has been improved.
