The objective of this work is to determine the performance of magnetic brakes in small wind turbines for various speeds. Finally, the quality of electric power produce can be enhanced by exact control of turbine`s rotor speed given by the magnetic brakes. Findings: Simulations have done using the various controllers comprising Proportional Integral Derivative (PID) Controller, Proportional Integral Controller, Fuzzy Logic (FL) Controller and Non Linear Controller in Mat lab Simulink. A comparative study is then made for the above simulations and obtained a conclusion that PID is the best choice. Besides this, a turning is made for PID controller using bacterial Fragmentation Algorithm and the best fit results are obtained. With such a controller inserted in our system, the system can have its optimum performance even at stall conditions. Applications/Improvements: With such a controller inserted in our system, the system can have its optimum performance even at stall conditions.
