Description: DSP为TMS320F240,带编码器,电机是三相交流永磁同步电机
欢迎大家一起讨论!!!!!
这是ASM文件,可不是PDF文件,你可以直接用.
如果用TMS320LF2407A有些地方指令要修改一下-DSP TMS320F240, with encoder, Three-phase AC motor is a permanent magnet synchronous motor welcome everyone to join in the discussion !!!!! This is the ASM paper that not PDF files, You can directly use. If TMS320LF2407A some directives have to adapt

Description: 1、 由于后级采样电子电路将正弦波整形为方波，因此模拟电路可直接输出频率可调的方波给后级。
2、 三相交流发动机由于发电绕组是120度对称安装，其输出的三相波形为相隔120度的三相正旋波，因此模拟电路必须输出三相相序对应的方波。
3、 三相交流发动机发出的三相交流电压相序隐含着电机的旋转方向，因此输出方波的相序应可调，以适应电机旋转方向的变化。
4、 后级采样电路为脉冲计数方式，为确保计数的准确性，模拟电路应输出占空比为50％的标准方波。
-1, after the class as a result of sampling shaping electronic circuit for the square wave to sine wave, so analog circuits can be directly adjustable output frequency square wave to the after-class. 2, three-phase AC motor windings as a result of power generation is 120 degrees symmetrical installation, the output waveform for the three-phase three-phase 120 degrees apart are chiral, so analog circuits must be three-phase output phase sequence corresponding square. 3, three-phase AC motors issued three-phase AC voltage phase sequence implied a motor rotation direction, so the output square wave of phase sequence should be adjustable to adapt to changes in the direction of motor rotation. 4, after the level sampling circuit for the pulse counting mode, in order to ensure the accuracy of counting, analog circuits should output 50 duty cycle for the standard square wave.

Description: 介绍了一种基于锁频锁相环(FPLL)的载波跟踪算法。频率跟踪模块可以适应较大动态范围的频率变化，基于软件的数控振荡器(NCO)模块可以达到极高的频率跟踪精度。由于有锁频环的频率牵引，锁相环路滤波器可以设计得很窄，具有很好的抑噪性能，满足精确跟踪载波相位的要求。因此，该基于FPLL的载波跟踪算法可以适应信号存在较大的动态范围和噪声干扰的应用环境；同时，其鉴频鉴相算法表达式简单，易于用可编程数字器件实现。-Introduce an approach based on frequency-locking phase-locked loop (FPLL) carrier tracking algorithm. Frequency tracking module can adapt to a larger dynamic range of the frequency change, software-based numerical control oscillator (NCO) module can achieve the very high frequency tracking accuracy. Because of the frequency lock loop traction PLL filter can be designed very narrow, with very good noise suppression performance, to meet the precise requirements of carrier phase tracking. Therefore, the FPLL carrier-based tracking algorithm can be adapted to signal the existence of a larger dynamic range and noise of the application environment at the same time, the PFD algorithm expression is simple, easy to use programmable digital devices.
