针对齿轮箱故障诊断的问题，提出了一种基于BP神经网络和DS 证据理论的不确定性信息融合方法。(In order to realize a stable and effective gearbox fault diagnosis system, an uncertain information fusion method based on BP neural network and modified DS evidence theory is proposed.)

说明：  按照逐次逼近法主回路开环，单回路整定副控制器，建立simulink仿真。(According to the successive approximation method, the main loop is open-loop and the sub-controller is tuned in a single loop, and the Simulink simulation is established.)

说明：  针对已知多频率正弦信号的频谱，设计相应的FIR滤波器(凯塞窗函数法设计低通,高通，带通滤波器，分别提取信号并绘制频域和时域曲线)按要求进行滤波。 根据已知滤波器的性能指标设计IIR数字滤波器(双线性变换法设计巴特沃斯低通IIR数字滤波器)，并对心电图信号进行滤波处理；(For known more frequency sinusoidal signal spectrum, to design the corresponding FIR filter (Kaiser window function method of designing low-pass, high-pass, band-pass filter, respectively, to extract the signal curve) and draw the frequency domain and time domain filtering according to the known filter in accordance with requirements of performance index design of IIR digital filter (bilinear transformation method to design butterworth low-pass IIR digital filter), and to filter the ecg signal)
