阐述基于DSP28335的电力滤波器测控系统的设计,外接传感器、数模转换、通信模块,实现采集与处理滤波器的工作数据,利用闭环前馈解耦控制器输出开关量控制指令,从而实现系统功能。测试表明,在DSP系统的控制下,经由电力滤波器的谐波量大幅减少,系统测量参数的最大相对误差约为0.57%,控制精度更高。

This paper describes the design of a power filter measurement and control system based on DSP28335,which includes external sensors,digital to analog conversion,and communication modules to collect and process the working data of the filter.The closed-loop feedforward decoupling controller is used to output switch control commands,thereby achieving system functions.Tests have shown that under the control of the DSP system,the amount of harmonics passing through the power filter is significantly reduced,and the maximum relative error of the system measurement parameters is about 0.57%,resulting in higher control accuracy.
