用VHDL语言来实现PID算法，文件包含了仿真的所有结果-VHDL language used to implement PID algorithm, the file contains all the simulation results. . .

用VHDL语言编写的模糊PID程序代码。成功调试，运行良好。-The source code of Fuzzy_pid in VHDL.Simulation was successful.

基于FPGA的PWM控制器设计，包含ADC0820模块，按键扫描，PID，PWM控制器等模块，VHDL语言完成，已仿真通过-PWM controller design based on FPGA, including ADC0820 module, key scan, PID, PWM controllers and other modules, VHDL language completed, through simulation

Simulation of the effect is very good, The IMC - PID is using the internal model control principle for PID parameters is calculated, Calculating a target and ocean echo power spectral density.
