Abstract
This paper presents the development of fractional order PIλDμ and fuzzy- controllers for control of dynamic plant. The fractional order derivative and integral are described. The designs of fractional order PIλDμ - and fuzzy controllers have been done. The parameters of fractional order controllers are turned using a real coded Genetic Algorithm (GA). The performances of the proposed control systems are illustrated through application examples. Fractional calculus has shown improvement in time response characteristics of feedback control system through the use of non-integer order derivatives and integrals.
Keywords: Fuzzy controller, fractional calculus, feedback control.
