Fuzzy Logic Controlled Zeta Converter fed DC-Motor Drive System with reduced Steady-State-error

Abstract

Zeta-converter finds a way between DC-source and DC-Motor to step-up and match the motor-voltage. This work proposes QBC between the DC source and DCM. The DC output is boosted by ZCS. The DC yield of ZC is provided to the DC-Motor. In-this-work, different-control-strategies for Zeta-Converter fed DC-Motor (ZC--DCM) such as ‘fractional-order-PID(FO--PID) controller’, ‘Hysteresis-controlle r(HC)’ & ‘-Fuzzy-logic- controller(F-LC)’ is exploited to sustain the constant yield-speed of the ZC--DCM. Also, the load disturbance is introduced to analyze the performance of ZC--DCM driven by different controllers. “-The-simulation of ZC--DCM has been done utilizing -MATLAB/-Simulink-software”. The objective of the present work is to enhance the closed-loop response of ZC--DCM using suitable-controller. Outcome reveals that the F-L-based ZC--DCM has good-performance, when compared to the FO--PID &Hysteresis-controller based ZC--DCM.
