摘要
对基于TMS320LF2407A DSP实现带有颤振的PWM驱动的控制器进行研究.根据感性负载的电流特性,分别导出了正弦波和三角波包络线的独立颤振的核心算法,并集成于DSP内核,且对PWM输出波形进行了数值仿真.该控制器特别适合于数字信号处理与控制系统.
The paper presents a research of a controller which has the drive of the pulse width modulation with dither based on TMS320LF2407A DSP.According to the inductive load current characteristic,detrudes the independent dither core algorithm when the enveloping curve are sine wave and pyramidal wave,then integrated the core algorithm in the core of the DSP,and gives the numerical value simulation about the output wave.The controller especially adapts to digital signal processing and controlling system.
