摘　　要：针对磁链估计方法在直接转矩控制方面的不足,本文对定子磁链设计电压和电流结合的优化模型,可获得较精确的定子磁链.基于此种优化磁链估算的方法,从直接转矩控制的基本原理和感应电机的多变量数学模型入手,通过Matlab建立了一个直接转矩调速系统,验证了此磁链观测器下的调速系统具有良好鲁棒性和动静态适应性能.For flux estimation method in the field of direct torque control was insufficient,in this paper,the stator flux linkage model was combined with the optimization of voltage and current,and stator flux could be obtained accurately.This paper was based on the optimization flux linkage method,starting from the basic principle of direct control torque and the multivariable model of asynchronous machine,a direct torque control was established based on Matlab system,this flux observer was verified under the speed control system with good dynamic,static performance and strong robustness capability.
