吴捷,姜智坚.感应电机调速系统新型滑动模解耦与自校正控制.中国电机工程学报1999 ( 1 ) - Motion control is a comprehensive subject . modern ac drive is a important embranchment in the field of motion control . however , it is difficult to rea1ize high - performance ac drive systems because induction motors are a kind of strongly - coupled nonlinear system with many variables and the torque is not easy to control . with vector control technology decoupling and torque control of ac motor are solved . the basic idea of vector control is that three - phase system is equiva1ent to two - phase system by coordinate transformation and it realizes the decoupling between field current and torque current of the stator in order to control the flux and current respectively , thus induction motor can be considered dc motor and high performance is achieved easily . with the progress of electric and electronic technology and the development of computer , high - integrated special modules and high - precision digital signal processor ( dsp ) are applied to ac drive so that vector control has been developed rapidly
但是高性能的交流调速系统实现很困难，这是因为交流电机是多变量、强耦合的非线性系统，不易实现高性能转矩控制。矢量控制技术则解决了交流电机解耦与转矩控制问题，其基本思路? ?应用坐标变换将三相等效为二相，实现定子励磁电流分量与转矩电流分量之间的解耦，达到对交流电机磁链与电流分别控制的目的，交流电机等效为直流电机实现高性能调速。随着电力电子技术的进步，计算机技术飞跃发展，高度集成的专用模块和高精度的数字信号处理器应用于交流传动系统中，促进矢量控制迅猛发展，日趋成熟。
