Paper Abstract

One of the main factors that affect the performance of stabilized Line-of-Sight (LOS) control system is disturbance torque. Firstly, the transfer function between disturbance torque and angular velocity of LOS is given by establishing the system dynamics model. Secondly, we investigate the characteristics of disturbance torque for small inertial Line-of-Sight control system. Thirdly, an application of disturbance observer is presented to compensate for disturbance, such as friction and mass imbalance. In this paper, consider only friction. Simulation is made by using the friction model output as disturbance input. In the course of Matlab simulation, the compensation by using disturbance observer improves the overall stabilization performance of the system. The RMS value of the velocity error has decreased to 10%.
