Modeling Brushless Direct Current Motor Of A Guided System

Fin actuation systems are used to direct the desired target of guided munitions. In these systems, mainly brushless direct current motors are used because of their high efficiency. In this study, the motor model has been created so that the form of the control method back EMF is ideal trapezoidal and it is driven with a six-step voltage inverter. The ideal back EMF form was obtained from the motor speed and rotor angle. PI control is used as a speed controller. In the next study, parameters such as eddy currents and hysteresis losses are also included in the model and it is aimed to obtain a model that is closer to the reality.
