检测脉冲 meaning in Chinese
detecting pulse
Examples
- According to the distribution of local impulse noise , an adaptive chord deviation method is used to avoid redundant detection or missing of impulse noise at the quick rising , descending or broken line area of data set
摘要针对现有脉冲噪声滤波算法在处理大斜率区域和断线型激光扫描数据中存在的多判和漏判问题，提出了一种有效检测脉冲噪声的方法。 - Regard how to structure the control system of sensorless bldcm with dsp - tms320f240 as the centre in this paper , the detailed argumentation course of the motor startup , bemf terminal voltage measurement and control strategy is given out , give and pay concrete details for the software and hardware realization and experimental result . in order to treat the bldcm control system with dsp clearly , the full paper divides into six chapters altogether : chapter one , introduceing the development course , the structure characteristic and operation principle , etc . of bldcm in the introduction ; chapter two , directed against the startup issue of bldcm , the chapter give and publish the rotor measure pulse orients technology for motor startup in detail ; chapter three , proceed with mathematics model of the bldcm , expounding the control schemes ; chapter four , two important devices introducing : dsp ( 240 tms320f ) and power invertor control chip ( ir2131s ) ; chapter five , give and publish the detail of hardwares of control system ; chapter six , by ccs ide of ti , realize the control schemes in the front chapters with software , offere the procedure flow chart of main subroutine and some key place of programming , the experiment result in addition
全文共分六章：第一章、绪论中介绍了bldcm的发展历程、电机本身的结构特点和工作原理等；第二章、针对五位置传感器bldcm的起动问题，文中详细给出了检测脉冲转子定位起动技术；第三章、从电机的数学模型入手，详细论述了反电动势端电压法和系统的控制策略；第四章、介绍了硬件实现中的两个重要器件： dsp ( tms320f240 )和功率管逆变器控制芯片( ir2131s ) ；第五章、详细给出了控制系统的硬件实现细节；第六章、利用ti提供的ccs集成开发环境，将前面章节的控制方案用软件加以实现，给出了主要部分的程序流程图和一些编程要点以及实验结果。
