| The of system electro-optic tricking servo platform become more important for the navy of many country, With the development of the television cameras and infrared imager, The servo stabilized-platform coupled with the of intuitive and high-precision provide precise instruction of the target for the ship's air defence system, The data can also be sent to other command and control system for tracking the target, but also suitable for observation and identification, which can be used to identify military targets and civilian targets to monitor the effects of war weapons, especially in the short-range real-time image provided by photo-electric sensors is to maintain the bridge and the commander of naval staff situational awareness is an important means. In addition electro-optic technology can be used to record images of the event can be used after the incident, and given the notes can also be used as evidence.This paper mainly introduce the research and design of a Shipborne electro-optical tracker servo system, according to the system achieve the main functions and to achieve the performance targets for analysis of the principles and design of hardware and software. based PC104 digital control system. Theoretical analysis of the dual-axis stabilized platform for the motor carrier of the principle of segregation, a precision and stability of the servo system performance requirements for the design of servo system provides a theoretical basis; system in accordance with the requirements of the design of the airborne platform for optical servo system The hardware circuit; through experiments and theoretical analysis to determine how to overcome the friction moment is the impact of this on-board systems to improve accuracy and stability to solve the first problem and solve this problem, proposed the use of digital encoders composition of the gun the speed of inner ring, and with relatively gyro inertial measurement platform space component of the speed of rotation ring, that is, the stability of the ring double loop control method, combined with non-linear acceleration compensation technology, is expected to achieve the targets required by the stability of accuracy; as to further improve To investigate the effect of control. For miss distance infrared tracking servo system with a relative 6 delay, delay in the analysis of the tracking system performance, and to that end made use of adaptive filter to predict compensation; theory, an analysis of convergence , And the algorithm is given in the form of standardized; used under the control algorithms using C language was designed and implemented on-board optical platform of stability and tracking servo system software.
