为提高过程控制的响应速度,提出了一种基于现场可编程模拟阵列(FPAA)模糊自整定PID控制器的硬件实现方法.在8块AN221E04芯片中实现模拟乘法器,求小求和以及除法等单元电路,由各单元电路组合成完整的控制器.作为硬件电路,该控制器与软件编程实现的模糊PID控制器相比具有很强的实时性;作为纯模拟电路,该控制器内部传输信号均为连续值的模拟量,不需要A/D,D/A转换电路,与采用数字电路实现的控制器相比具有电路简单,运算速度快的特点.仿真实验结果表明:基于FPAA的模糊自整定PID控制器超调量小,稳态误差小,控制器响应时间降到了微秒级

To improve the response rate of process control,a method for hardware implementation of fuzzy self-tuning PID controller based on Field Programmable Analog Array（FPAA） was proposed.All cell circuits such as analog multiplier,seeking small and sum,divider were implemented on 8 AN221E04s,and then an intact controller was assembled with the cell circuits.As a hardware circuit,this controller has a better real-time quality than that of the fuzzy PID controller based on software programming;As an analog circuit,it does not need to be equipped with...
