Description: 机电传感器通常用于获取转子位置/速度的内置式永磁同步电机（ IPMSMs ）的高性能控制
车辆系统。然而，使用这些传感器中的增加的成本，尺寸，重量，布线复杂性并减少了IPMSM驱动系统的机械鲁棒性。这些问题连同
一些实用的要求，例如，调速范围广，极端
环境温度和不利的负载条件下，使传感器控制方案可取。本文提出了一种扩展的反电动势（ EMF ）为基础的滑模
转子位置观测器IPMSMs的无传感器矢量控制。
基于滤波器的特性，一个强大的补偿算法的开发，以改善滑动方式观测器（SMO）的性能。多级滤波器和双滤波器的计划被设计的补偿算法，以进一步改善稳态和瞬态性能，分别。建议SMO和补偿算法通过在MATLAB的Simulink仿真，以及对实验进行验证
实用的永磁同步电动机驱动系统-Electromechanical sensors are commonly used to obtain rotor position/speed for high-performance control of interior permanent magnet synchronous machines (IPMSMs) in
vehicle systems. However, the use of these sensors increases the cost, size, weight, wiring complexity and reduces the mechanical robustness of IPMSM drive systems. These issues, together with
some practical requirements, e.g., wide speed range, extreme
environment temperature, and adverse loading conditions, make a sensorless control scheme desirable. This paper proposes an extended back electromotive force (EMF)-based sliding mode
rotor position observer for sensorless vector control of IPMSMs.
Based on filter characteristics, a robust compensation algorithm is developed to improve the performance of the sliding-mode observer (SMO). Multistage-filter and dual-filter schemes are designed to further improve the steady-state and transient performance, respectively, of the compensation algorithms. The proposed SMO and c Platform: |

Description: 共振解调法诊断轴承损伤类故障的原理概述如下:当轴承某一元件表面出现局部损伤时，在受载运行过程中要撞击与之相互作用的其它元件表面，产生冲击脉冲力，由于冲击脉冲力的频带很宽，必然包含轴承外圈、传感器甚至附加的谐振器等的固有频率而激起这个测振系统的高频固有振动。根据实际情况可以选择某一高频固有振动作为研究对象，通过中心频率等于该固有频率的带通滤波器把该固有振动分离出来。然后进行包络解调，去除高频衰减振动的频率成分，得到只包含故障特征信息的低频包络信号，对这一包络信号进行频谱分析便可以容易地诊断出轴承的故障来。-The principle of resonance demodulation method in the diagnosis of bearing damage such failure overview is as follows: when the bearing surface of a local damage, in the process of loading operation to hit with other elements of the interaction of surface, impact pulse power, due to the impact pulse frequency band is very wide, inevitably contains the bearing outer ring, sensors and even additional resonator and stir up the natural frequency of the vibration system of the high frequency vibration mode.A high frequency vibration mode can be selected according to actual situation as the research object, through the center frequency is equal to the natural frequency of the bandpass filter to separate the natural vibration.Then envelope demodulation, frequency components to remove the high frequency vibration attenuation, get only includes fault feature information of low frequency envelope signal, the envelope signal spectrum analysis can be easily diagnosed bearing failure.
