| Abstract: |
| According to the principle of traditional fuzzy reasoning,a modularized design of high -speed fuzzy reasoning based on CPLD(Complex Programmable Logic Device) for fault diagnosis expert system is presented.Applying the ROM -function -transform theory,it realizes the fuzzy transform and calculation of different data and different types in one ROM,and implements the coordination and control of fuzzy reasoning with CPLD,which is divided into several sub -blocks by generalization.The reasoning process,implemented by software traditionally,is thus built by hardware.Experiments validate that the fuzzy reasoning design is simple in implementation,especially suitable for on -line diagnosis systems based on singlechip or DSP,and the reasoning speed is faster than traditional ones. |
