变换模块 本模块包含两部分内容IM0623
(1)变换模块
本模块包含两部分内容:利用 反变换规则将 坐标系下的两相电流转换成三相电流;利用间接矢量控制,得到转子角位移,公式如下(2) 电流滞环控制器(Hysteresis current controller)模块(3) 电压源型逆变器(Voltage sourse inverter,VSI)模块
(4) 变换模块(5) 感应电机(IM)模块
该感应电机模型是基于交流电机的电路方程、转矩方程以及运动方程建立起来的。该仿真模块为一个三输入、六输出的系统子模块。输入为 坐标系中定子电压,输出则是 坐标系中的转子电流和转子磁链,以及输出的转矩。(6) 电流反馈模块(7)速度控制器模块

Changes-in-the-signal-to-noise-ratio
等间距线性阵列,阵元数M=8,阵元间距d= λ /2,等幅加权,目标方位φr =0°。产生空间白噪声矢量(复高斯分布)。
设阵列信号矢量元素s(m)=exp[j mψr],其信号幅度为1,该阵元接收机附加的高斯噪声为n(m)=nmr+jnmi,其中实虚部均为独立同分布N(0, σ2)的高斯随机数,则该通道合成信号x(m)=s(m) + n(m),其中信噪比为:
SNR = 10 lg[1/(2σ2)] = – 3 – 10 lg(σ2) (dB)
(The spacing of the linear array, and the array element number M = 8, the array element spacing d = λ/2, equal amplitude weighted target azimuth φR = 0. Space generated white noise vector (complex Gaussian distribution). Let array signal vector elements s (m) = exp [j mψr], the signal amplitude, the element receiver additional Gaussian noise n (m) = nmr+jnmi which the real and imaginary parts are independent and identically distributed N ( Gaussian random numbers of 0, σ2), the channel the synthesis signal x (m) = s (m) the PPLS n (m), where SNR is: SNR = 10 lg [1/(2σ2)] =- 3- 10 lg (σ2) (dB))
