  3. 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
