异步电机的双闭环控制
矢量控制是目前交流电机的先进控制方式,一般将含有矢量变换的交流电机控制都称 之为矢量控制,实际上只有建立在等效直流机模型上,并按转子磁场准确定向的控制,电机才能获得最优的动态性能。
矢量控制的基本思路是以产生相同的旋转磁动势为准则,将异步电机在静止三相坐标系上的定子交流电流通过坐标变换等效成同步旋转坐标系上的直流电流,分别加以控制,以达到直流电机的控制效果。(Vector control is an advanced control method of AC motor at present. Generally, vector control is called vector control. In fact, only based on the equivalent DC motor model and accurately oriented control according to the rotor magnetic field, can the motor obtain the optimal dynamic performance.
The basic idea of vector control is to generate the same rotating magnetomotive force as the criterion. The stator AC current of asynchronous motor in the static three-phase coordinate system is converted into DC current in the synchronous rotating coordinate system by coordinate transformation, and then controlled separately to achieve the control effect of DC motor.)

一种适合TDMA系统突发信号检测的改进算法
说明: 与连续信号的解调相比,短时突发信号持续时间短,不适用性能良好的反馈环路算法,需要使用前向幵环算法。与一般突发信号相比,短时突发信号没有训练序列、同步头等辅助信息,所有参数需要利用有限的数据估计。与合作通信相比,盲接收信号参数的初始偏差较大,估计范围小的算法不适用。每个突发包的数据有限,解调过程不允许丢失任何符号。(Compared with the demodulation of continuous signal, short burst signal has a shorter duration and is not suitable for the feedback loop algorithm with good performance. Forward loop algorithm is needed.)

radpattern
RADPATTERN - radiations patterns, total radiated power
Syntax:
radpattern
Description:
RADPATTERN should be run after IMPEDANCE. It uses the MoM soulution
obtained previously in order to compute the far fields. RADPATTERN
finds the far field at a given frequency that needs to be specified
below.Also, the observation sphere(radius) or circle (radius/plane)
need to be specified as well.
RADPATTERN finds:
- total radiated power over a large sphere (sphere mesh is given in subfolder CODES)
- antenna gain or absolute directivity in certain planes, including
co-polar field and cross-polar field.
