Abstract
AbstractRecently, lots of researches have been investigated for the BLDCM system. The purpose of this paper is to design a controller which can reduce the torque and speed fluctuation when load changes suddenly. The advantage of traditional PI controller is that there is no static error, but the dynamic performance is not good especially the load changes suddenly. The advantage of Fuzzy controller is the dynamic performance is good when the load changes suddenly, but there exists static error. Compared to traditional PI and Fuzzy controller, the new algorithm based on Fuzzy-PI can improve the dynamic performance of the system. Also, the speed and torque fluctuations are reduced at the same time. Simulation results show that the validity of the proposed method. The new control algorithm can be used in BLDC control system. Simulation results can provide reference for the actual BLDC control system.KeywordsFuzzy-PI controlSimulinkBLDCM
