矢量角 meaning in Chinese

vector angle
vectorial angle

On the bases of analyzing two typical direct estimation methods of rotor speed , a novel sensorless technique of permanent magnet synchronous motor ( pmsm ) direct torque control ( dtc ) is put forward in this paper
通过分别计算出定子磁链矢量角位移与转矩角，将后者从前者中减去得到转子磁链矢量的角位移进而得到转子速度信号，并采用改进积分器取代传统的积分器。
Cfd is also used to get the data of performance parameters of the nozzle at different nozzle pressure ratio , different nozzle area ratio and different geometric defected angle . the theory of function approximation is used to establish the transient model of thrust vectoring with the data calculated
本文通过cfd计算获得矢量喷管的性能参数，如流量系数、推力系数以及有效推力矢量角等与矢量喷管压比、面积比以及几何偏转角之间的关系数据，并利用函数逼近理论建立了矢量喷管的动态数学模型。
