关于四旋翼飞行器的控制仿真，串级PID算法。有相关文献。(Control simulation of four rotor aircraft, cascade PID algorithm. There are relevant documents.)

这个函数返回n点2dw波段的傅里叶变换的DFT样本序列。通常情况下，以插值点的方式进行放大。(This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw.)
