DECENTRALIZED FUZZY CONTROL OF MULTIVARIABLE SYSTEMS BY ACTIVE DECOMPOSITION OF CONTROL LAWS

This paper considers the problem of decentralized fuzzy control of mul tivariable systems. Some definitions and theorems with regard to this problem are given. Decentralized fuzzy control algorithms, based on ac tive decomposition of control laws, are presented and illustrated by n umerical examples. The algorithms use local sets of fuzzy relations, d ecoupling the influence of state on control variables when added to th e original fuzzy relations. It is shown that the number of fuzzy relat ions is significantly reduced and thus real-time control implementatio n is facilitated.
