Linguistic Hedge Fuzzy Logic Controller in CMOS Technology

In this paper. circttit implementation of lingtistic hedge fuzuy logic controller (FLC), in a mixed-signal circuit design approach, is presented. This type of FLC can be reali:ed with a lower de.sign complexity and a smaller harduare compared with lhe conventional FLCs A tuneable triangular and trape:oidal shape Juifier is designecl and Linguistic hedges are used to dynamically modifu the shape of membershipfunclions according to the feedback signals from lhe controltecl plan. Digital circuits are also adopted lo implemenl programmable units The circuits are strpplied with l.5v power sttpply using 0 35u CMOS technologt
