Abstract: This project deals with modelling and performance evaluation of solar powered BMBLDC drive systems using MATLAB and its toolbox SIMULINK. The system consist of mathematical model of photo voltaic source, boost converter, BLDC motor, inverter, current controller an speed/torque controller is used for proposed model of solar powered PMBLDC drive system. The motor is controlled through a hysteresis current loop and an outer speed loop with a pi type controller. The proportional and integral gains are set to their optimal values. This proposed model can be projected to unproblematic design tool for the development of solar powered PMBLDC drive system.
