The model presents speed control of brushless DC motor. There is complete dynamic model of brushless DC motor. Actual speed of motor is compared with reference speed to control three phase inverter to adjust the terminal voltage. This model of BLDC motor can be used in sensorless control of BLDC motor as well.
I am working with a PWM-Duty cycle controlled model of BLDC. I saw your model and I am confused by the way you have modelled it. the input to the BLDC block is supposed to be a 3 phase DC voltage and you have made it with a 2-line DC input.
will you be kind enough to explain me and help me understand the idea behind this model.
