Electro-Mechanical Actuator Servo Design For Launch Vehicle Application

Abstract: In a launch vehicle the Electro-Mechanical Actuation (EMA) system gimbals the rocket nozzle and provides accurate steering of the vehicle. The adequate amount of force or thrust at the gimbal point is obtained by the small rotation of the gimbal. The force generated from the EMA system stabilizes and steers the launch vehicle in the required direction in to overcome the wind-gust disturbances and balance the aerodynamic movements. The mathematical model of the linear actuator is considered for the servo system design. In this paper the servo design of the actuation system is carried out for the launch vehicle application. The servo system integrates actuators, sensors and embedded intelligent systems for control, optimization and supervision which aim in improving the performance of the system. Due to high reliability demands of such systems, accurate supervision and fault diagnosis concepts are of particular importance.
