Learning and Tuning Fuzzy Logic Controllers Through Reinforcement

Fuzzy Logic controller

Step one: fuzzification(encoding)

In coding the values from the sensors, one transforms the values of the sensors measurement by using the linguistic labels in the rule predictions. This process is commonly called fuzzification or encoding. The fuzzification stage requires matching the sensor measurement against the menbership functions of linguistic labels.

In modeling the hunman expert operator's knowledge, fuzzy control rules of the form
IF Error is small AND Change-in-error is small THEN
Force is small

can be used
