摘要
提出了一种用数字逻辑电路设计模糊控制器的方法。该模糊控制器电路不用ＣＰＵ，全部算法由数字逻辑电路实现，具有运算速度快的特点，适合于需要高速控制的场合。该模糊控制器电路具有被激活的规则自动生成功能，不需要大规模的ＲＡＭ或ＲＯＭ存储模糊规则，电路规模小，易于实现，特别适合于输出控制量为离散值的应用场合。已在一片ＦＰＧＡＸｉｌｉｎｘ４０１０ＰＧ１９１－６上实现了该模糊控制器电路，并成功地应用于温控系统。
A technique to design a fuzzy controller by using digital logic circuits is proposed.No CPU is needed for the fuzzy controller circuit. All algorithms are realized for high speed by digital logic circuits. Automatic generation of fuzzy rules is obtained for the circuit,thus eliminating the need for large scale RAM's or ROM's to store fuzzy rules. The controller is very useful where output control is discrete. Finally, the circuit has been implemented in an FPGA Xilinx 4010 PG191-6 chip and successfully applied to a temperature controlled system.
