Abstract	A frequency response provides control engineers with the ability to analyze and design control systems in the frequency domain by describing the steady-state response of a system to sinusoidal inputs of varying frequencies .A system's frequency response is represented by two graphs: one that illustrates magnitude and the other that illustrates phase. The transfer function's phasor representation may be readily calculated at any frequency. The Electro-Mechanical Actuator (EMA) is a widely used position servo-system that is used extensively in several sectors. The control architecture of EMA typically employs a cascaded structure, where location, velocity, and current loops are incorporated, They are implemented using PID controllers.. The BLDCM is increasingly being used in EMA systems because to its compact size, superior efficiency, high power density, and less rotor inertia. This study introduces the development of a Position Servo-System for a Brushless DC Motor (PSSBLDCM) intended for use in an Electromechanical Actuator (EMA). Therefore, to fulfill the frequency response requirement of the position loop, the frequency responses of the velocity loop and current loop are established. A frequency domain approach is then used to construct the PID controllers. The system is simulated using SIMULINK, while the experimental system is created using the DSP TMS320VC33 and FPGA CYCLONEIIEP2C35. The results suggest that the PSSBLDCM is able to fulfill the requirements.
