利用载波移相调制产生pwm波，驱动开关管，实现五电平( Using carrier phase shift modulation to generate PWM wave, drive the switch tube, realize the five level Using carrier phase shift modulation to generate PWM wave, drive the switch tube, realize the five level )

幅度调制解调：用两种方法实现解调包络检波和相干(Amplitude modulation and demodulation: two ways to achieve envelope demodulation and coherent demodulation)

本文提出一种新的智能故障诊断方法,基于统计分析,提出了一种改进的距离的评价技术和适应性类神经模糊推论系统(简称ANFIS)。该方法包括三个阶段。　(This paper presents a new approach to intelligent fault diagnosis based on statistics analysis, an improved distance evaluation technique and adaptive neuro-fuzzy inference system (ANFIS). The approach consists of three stages. First, different features, including time-domain statistical characteristics, frequency-domain statistical characteristics and empirical mode decomposition (EMD) energy)
