Parameters identification BLDC motor: Instrumentations and transfer functions

One of the steps that must be taken in optimizing the speed control of the Brushless DC motor (BLDC) Motor is to mathematically model. The purpose of this research is to get the mathematical modeling of BLDC motor with 350 watts of power in the form of transfer function. The method used to obtain the transfer function is to identify the input and output data. The identification is done by designing and placing current sensors, voltages and motor speeds in the prototype BLDC motor speed control. The measured input data includes current and voltage, while the output data is the engine speed (RPM). By adjusting the pulse width modulation value (PWM), a change in the speed of the BLDC motor is affected. From the process of research in the form of instrumentation on hardware prototype and simulation with application program Matlab System Identification Toolbox (SIT), successfully obtained mathematical modeling in the form of transfer function.
