搭建永磁同步电机的直接转矩控制仿真模型
1,实测电流经过3/2变换得到alpha-beta轴上的电流;
2,估计模块中包含定子磁链和电磁转矩的估算,其中,定子磁链观测是采用基于转子位置和定子电流的磁链估计,电磁转矩直接在alpha-beta轴上计算;
3,转速调节模块和转矩调节模块直接采用PI调节器;
4,预期电压矢量估计模块,根据k时刻的磁链幅值与相位和k+1时刻的磁链幅值和相位计算出来的;
5,SVMPWM是空间电压矢量调制模块,实现空间任意角度任意大小的电压矢量,从而控制磁链轨迹近似为圆型;
6,逆变器模块和电机模块均采用系统自带的;(Build a permanent magnet synchronous motor direct torque control simulation model, the measured current after 3/2 transform the current alpha-beta axis estimated module included in the estimation of the stator flux and the electromagnetic torque, stator flux chain observation is based on the position of the rotor and the stator current flux estimates, the electromagnetic torque directly in the alpha-beta axis 3 speed controller module and torque adjustment module directly using the PI regulator expected voltage vector estimation module , calculated according to the time k flux amplitude the phase and k+1 time flux amplitude and phase 5, SVMPWM the space voltage vector modulation module voltage vector space at any angle of any size, thereby controlling the flux path approximate round inverter module and motor module system comes )

Microstrip antenna
说明: matlab编写的FDTD(时域有限差分法)程序,可以实现完整天线方向图和反射系数的计算,以贴片天线为例,对比了编写程序的反射系数与方向图和HFSS计算的反射系数与方向图,具有一致性。(FDTD (finite difference time domain) program compiled by Matlab can realize the calculation of complete antenna pattern and reflection coefficient. Taking patch antenna as an example, the reflection coefficient and pattern calculated by the program and HFSS are compared, which are consistent.)
