Simulation Model of Buck Converter Closed System Using PMBLDC Drive
نویسنده
چکیده
The PMBLDC motor is 3 phases, 4 poles, Y connected; trapezoidal back-EMF type of BLDC motor for automotive industry application is modeled and simulated in MATLAB / SIMULINK. A MATLAB program is developed to simulate the overall motor drive system. A closed loop speed control strategy is developed and simulated. The drive system is proposed with a buck converter topology. In this model the buck converter is used as a step-down DC voltage. A single neuron PI controller is used to control the speed. According to simulation and experimental results, the proposed strategy shows good self adapted track ability, also the structure of the drive is simplified. A detailed discussion about the simulation of the proposed drive system is presented.
