Design of Digital BLDCM Servo Control System

By analyzing the shortages of the current missile servomechanism which has complex structure,high machining accuracy,large volume weight,difficult technology,short lifetime,and the requirements of small volume and quality,high control precision,fast response which the low power missile thrust vector control requires for the servomechanism,a new digital servo control system using brushless DC motor as a servo motor,combined with the model number actual missile servo,power distribution systems based on DSP was presented.The control system was simulated and analyzed.The simulation results show that the system has a good dynamic and static characteristics,and the system design has feasibility.
