| 摘 要： | 基于双脉宽调制的客观需要,本文采用了PID补偿网络方法来对系统性能进行优化。构建闭环反馈的方式来提升直流输出的质量,同时使得整个系统保持更高的稳定性。本研究用增量代替微分的思想使数字补偿替代模拟补偿,根据DSP28335数字信号处理器的特点设计了产生双脉宽信号的方法,并通过仿真实验证明了PID补偿对系统的优化效果。

| Abstract: | Based on the objective needs of dual pulse width modulation, this paper uses the PID compensation network method to optimize the performance of the system, and constructs a closed-loop feedback method to improve the quality of DC output, while maintaining a higher stability of the whole system. In this paper, the idea of relacing differential with increment makes digital compensation replace anolog compensation. According to the characteristics of DSP28335 digital signal processor, a method of generating dual pulse width signal is designed. The simulation results show that the PID compensation is effective for the optimization of the system. |
