  5. 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

    但是高性能的交流調速系統實現很困難,是因為交流機是多變量、強耦合的線性系統,不易實現高性能轉矩控制。矢量控制技術則解決了交流機解耦與轉矩控制問題,其基思路? ?用坐標變換將三相等為二相,實現定子勵磁流分量與轉矩流分量之間的解耦,達到對交流機磁鏈與流分別控制的目的,交流機等為直流機實現高性能調速。隨著子技術的進步,計算機技術飛躍發展,高度集成的專用模塊和高精度的數字信號處理器用於交流傳動系統中,促進矢量控制迅猛發展,日趨成熟。
