  1. In dtc system, the concept of space vector is introduced to analyze and control the ac motor, the electromagnetic torque and flux are caculated and controlled in the stator reference frame, and the optimal pwm gating signas are generated to control the inverter according to the output of the bang - bang regulator. in this paper, the dtc system is designed based on dsp. a speed estimation method is derived detailedly and the sensorless speed close - loop control is conducted. in this system, there are some problems, such as flux drift and torque ripple. to resolve these problem, a modified flux caculation method and some measures such as speed lpf, torque slide filtering are adopted. the system performance is enhanced by these mersures

    直接轉矩控制採用空間矢量的概念來分析異步電機的數學模型和控制其各物理量,直接在定子坐標系中計算和控制轉矩和磁通,藉助于離散的兩點式調節( bang - bang控制)產生pwm信號,直接對逆變器的開關狀態進行優化控制,以獲得轉矩的高動態性能。本文採用dsp設計了直接轉矩控制系統,詳細推導了速度估計方法,進行了無速度傳感器的速度閉環控制。
