BBO Tuned FLC for Three Phase Rectifier

—Three Phase Rectifier in the power electronic system which used in many applications. Optimal for in Power Electronic System control strategy has been proposed for BBO-FLC based Three Phase Rectifier in Power Electronic System. Proposed Power Electronic System (PES) consists of input, isolation and output stages. In order to test dynamic performance of BBO-FLC based PES, simulation study was carried out by MATLAB/Simulink. The results obtained from the BBO-FLC based PES are not only superior in the rise time, settling time and overshoot but can prevent from voltage and has improved power quality. Embody for simulation of Fuzzy Logic Controller and he characterizes to obtain the optimal parameters of FLC. Biogeography Based Optimization BBO is a new intelligent technique for optimization, it can be used to tune the parameters in different fields. The main contribution of this work efforts the ability of BBO to design the parameters of FLC by determining the shapes of triangle memberships of the inputs and output. The results of optimal controller (BBO-FLC) compared with the other controllers designed by Genetic Algorithm GA which it is a powerful method has been found to solve the optimization problem. The implementation of BBO algorithm has been done by Mfile/Matlab, this program linked with SIMULINK to calculate the finesses function which has the complete mathematical system model has implemented using. The results show the excellent performance of BBO-FLC compared with GA-FLC and PI controller, also the proposed method was very fast and need a few number of iterations.
