摘　　要：介绍了基于FPGA的智能微生物发酵控制系统的全硬件实现。系统以Spartan-3A DSP FPGA为核心,对发酵过程中的重要的参数pH值、DO等进行实时在线检测与控制。针对微生物发酵过程中的时变性、非线性、延时性、随机性等特点,提出采用模糊神经网络的控制技术来实现对系统的精确控制。给出了基于Xilinx FPGA/CPLD开发平台和MAT-LAB/Simulink仿真环境进行DSP功能实现的方法和设计流程。实践表明:系统设计紧凑、可靠,具有较强的鲁棒性。A new hardware implementation of intelligent control system- for biology fermentation based on FPGA was intro- duced. Using Spartan-3A DSP FPGA as the kernel unit, this system was used for on-line measure and control of the important pa- rameters of the fermentation process, PH, Do, etc. In allusion to time-varying, time-lag and randomness of the biology fermenta- tion control process, fuzzy logical control technology was used. The design methods and flows of DSP core based Xilinx FPGA/ CPLD development platform and MATLAB/Simulink simulation environment were also introduced. The simulation showed that this system has the advantage of simple system architecture and good control performance, high accuracy and good robust.
