A brushless DC motor (known as BLDC) is a permanent magnet synchronous electric motor which is driven by direct current (DC) electricity, and it accomplishes an electronically controlled commutation system instead of a mechanical commutation system. Major of the BLDC applications are based on speed control like motors used in electric vehicles, washing machines, air conditioners, etc. For the speed regulation of BLDC, TMS320F2837xD and TMS320F28069M microcontrollers are used, which belong to the C2000 family. These microcontrollers are used to increase efficiency by reducing the system components and enabling a cost-effective design of intelligent controllers for three-phase motors. With these devices, digital vector control algorithms like field-oriented control (FOC) may be implemented with much more precision. By computing a dynamic model of the motor, the FOC algorithm maintains efficiency across a wide speed range and considers torque variations with transient phases. The ideas include strategies to get rid of the phase current sensors and switch to sensorless speed control with an observer. The proposed model simulations can be achieved using MATLAB simulation tools, Graphical User Interface (GUI) application and Code Composer Studio (CCS).
