Direct torque control uses the pure integral voltage model for torque observation. The problems of accumulate error and direct current excursions will cause the fluctuations of current and torque. A modified model of flux observation is put forward.

- 針對傳統的直接轉矩控制系統采用純積分的電壓模型作為磁鏈觀(guān)測器；存在著(zhù)誤差積累以及直流偏移；導致電流和轉矩的波動(dòng)問(wèn)題；提出了一種改進(jìn)的磁鏈觀(guān)測器；該觀(guān)測器由兩個(gè)模型組成；開(kāi)環(huán)電流模型用于低速范圍內觀(guān)測磁鏈；自適應電壓模型用于全速范圍內觀(guān)測磁鏈.
