Abstract: In this paper brushless DC motor(BLDCM)actuation system as original motivation was analyzed in detail,to eliminate shortcoming and inadequate of DC motor.The mathematical model of BLDCM was established.The speed servo characteristics and anti d-disturbance of BLDCM was carried out in speed mode.The simulation results show that BLDCM with steady-state high precision and fast dynamic response fully meets indictor requirements of actuation system. Key Words: Brushless DC Motor;Actuation System;Speed Servo;Simulation
