：介绍了一种利用DSP控制的大容量蓄电池自动充电装置的设计。采用高频开关电源技术，给出了基于数 字信号处理器TMS320LF2407的充电装置控制系统的软、硬件设计。借助Matlab中的Simulink仿真工具，采用 在线模糊自整定技术对充电装置控制系统进行仿真，并将仿真结果应用于DSP控制器中，实现对Fuzzy-PID控 制的Kp、Ki、Kd参数的在线自整定，使充电方式能较好的模拟最佳充电曲线，达到理想效果。理论分析和试验都 表明，该充电装置能够有效地提高蓄电池的充电效率，加快充电速度。 (：An automatic charging equipment with high-capacity storage battery was designed through being controlled by DSP.Using the HF SPS(High-Frequency Switching Power Supply)，the software/hardware implementation of a TMS320LF2407 based controller system was introduced.With the tool-box of Simulink in Matlab，it adopts Fuzzy-PID methods to simulate the controlling system of charging system.Then the result of simulation will be used in DSP controller to realize self-control of the the parameters of Kp、Ki、Kd in PID controller so as to make the way of battery charging could simulate the excellent curve and reach ideal results.)

说明：  加循环前后缀和升采样程序，插入循环前后缀是将每个OFDM符号的前32个数据放到符号尾部，将每个OFDM符号的后32个数据放到符号头部，升采样是通过中间插零的方式实现(Cycle before adding the suffix and lift sampling program, insert the loop before the suffix is ??the first of each OFDM symbol data into the symbolic end of 32, after each OFDM symbol data into the symbols of 32 head or through the middle of the sampling way to achieve zero insertion)
