Research Of Self-Disturb-Objection LOS Stabilization Technology

The thesis discusses Self-Disturb-Objection LOS stabilization technology. This technology is mainly used in design of Los stabilization control system. At first, the development and basic working principle and component element and classification of electro-optical LOS stabilization system is explicated. Then, the current situation of this technology in home and broad is introduced. This thesis analyzes kinematics and dynamics of two-axis two-framework structure and two-axis four-framework structure and reflecting mirror structure and mass stabilization of electro-optical LOS stabilization system. This thesis analyses the element of influencing the precision of LOS stabilization and creates the model of control system. The thesis explicates Luenberger state observer and Ohnishi’s disturb observer and Ju-Kwang Park’disturb observer and method of using curvature model and nan’s nonlinear method. Their working principle and feature and common ground and difference are explicated. This thesis introduced a special self-disturb-observer being fit to LOS stabilization. The inputs signal of this method are current of motor and output of gyro, and it observers and compensates disturb. The thesis analyses and emulates this method and design circuits and introduced experimental method. The experiment of precision of using this method is done. Results of experiment indicate that this method increases precision of LOS stabilization clearly. Application and making more widespread of this technology is deserved.
