Geethu Biju Kumar, Baby Sebastian, Beena M Varghese

This paper describes the compensator design of Brushless DC motor based actuator in a position servo system. The work aims to develop the model of a BLDC motor presently used in launch vehicle application using the given specifications and design the suitable compensator in order to meet the requirements of launch vehicle. The servo analysis, compensator design and linear modelling of the electromechanical actuation based system are carried out. Compensation scheme is developed based on plant requirements and dynamics. Open loop plant and step response is observed. After compensation the system is found to meet all the requirements needed for launch vehicle applications. The simulation results are presented by using MATLAB/SIMULINK as the simulation tool.
