Fuzzy logic can make control engineering easier for many types of tasks and also add control where it was previously impractical, as applications such as fuzzy-controlled washing machines. Keeping in mind the inherent advantages of using fuzzy logic, a Fuzzy Logic Controller has been designed to control the duty cycle of the step-up chopper for the reasons mentioned above.
The control rules for the designing were framed based on a simulation study of a wind turbine generator set-up feeding a battery and a load. The scheme with the FLC was simulated in MATLAB using simulink and the built in block sets like the Power System Block sets. The duty cycle was found to vary as expected and the charging current to the battery was found to be optimum in all cases.
