High-speed reasoning fuzzy controller

摘要

A central processing unit 10 for outputting control signals so that all the control knowledge memories can operate in a burst mode, and a counter group 20, 30 for designating the addresses of the respective control knowledge memories in accordance with the output signal of the central processing unit , 40, 50, and 60), output values that have been stored in advance according to the address designation of the counter group, control rules of the conditional part, control rules of the conclusion part, membership function of each channel, A delay unit 90 for delaying the output signal of the roll counter for a time period during which all the channels corresponding to one control rule are accessed; And an IF channel counter, a THEN channel counter, a THEN label counter, and an IF, according to output signals of the memory, the THEN rule memory, and the IF belonging function memory, An IF MAX-MIN circuit and an alpha-cut memory 130 for storing the intermediate value after executing the fuzzy AND logic, a latch 150 for temporarily storing the output signal of the THEN belonging speed function memory, a MAX-A THEN MAX-MIN circuit 160 for executing fuzzy OR logic according to a signal input from the alpha-cut memory and the THEN belonging speed function memory; A high-speed reasoning fuzzy controller capable of dramatically improving the processing speed of fuzzy reasoning by hardware fuzzy inference by distributing control knowledge memory used in fuzzy inference and accessing these memories in burst mode.
