- 传统异步电机直接转矩控制多采用六边形磁链控制或六区间的圆形磁链控制，容易造 成转矩和磁链脉动过大，限制了其实用范围。针对此缺陷，本文采用矢量细分的方法，将传统的六电压矢量和六扇区细分为十二电压矢量和十二个扇区，制定了相应的矢量开关表，并通过 MATLAB 对其进行了仿真实验。仿真结果表明，基于矢量细分的异步电机直接转矩控制能够有效改善磁链轨迹，减小转矩脉动，提高系统控制性能。 -Conventional induction motor direct torque control multip

- 压频比控制方法非常适用于风机和泵等负载变化较慢的 应用场合。但对于需要快速动态响应的应用场合则效果 不佳。特别是在速度或转矩发生快速变化时，由于较高 的转差率则会导致较大的瞬态电流。如果同时对电机转 矩和磁通进行闭环控制，则可以在不产生大电流的条件 下实现快速的动态响应。矢量控制技术可以实现上述目 标，通常也被称作磁场定向控制（FOC）。-Voltage to frequency ratio control method is very suitable for fan

- 永磁同步电机直接转矩控制中引入SVPWM技术后，磁链和转矩脉动明显减小,且速度响应明显加快。这是由于传统的DTC系统釆用滞环控制器,每个周期选择一个幵关电压矢量,不能完全补偿转矩和磁链的误差 而后者采用PI控制器和SVPWM调制,可选择多个基本电压矢量来合成任意的电压矢量,能够更好的补偿误差。仿真结果说明,基于SVPWM的DTC系统在磁链幅值响应以及转矩响应上的改善效果很明显。-the impact of space voltage vector of the stator flux and t
