China engaged in electro-optical tracking servo-controlled studies have been 40 years, reached a certain level of skill, but in comparison with foreign countries, due to start shorter, or has a certain gap. With the enhanced mobility to track targets, resulting in the dynamic tracking error rapidly increases, the current control method has been gradually can not meet the requirements of control precision, how to improve tracking accuracy of servo control system, a steady beam to become the research hotspot in recent years. Electro-optical tracking servo control technology is widely used in the field of military technology, the technology in the research on China’s national defense construction has important significance.This paper introduces the technology to achieve beam stability at home and abroad Research, described the meaning of this research. And then electro-optical tracking servo control system structure, tracking manners described in detail, given the composition of the various links of the system mathematical model. Improving the beam stability of the most commonly used control methods for compound control systems introduction, and apply to different means of tracking the compound control method were introduced, discussed its advantages and disadvantages, on this basis, leads to the acceleration of information-based compound control method to improve the beam stability.Based on the delay to have a first-order inertia link fitting two-point method for DC torque motor model parameters were determined, method in accordance with frequency characteristics corrected link to configure your system parameters, of individual calibration loop to establish simulink simulation model. The output signal of the accelerometer test, due to a variety of interference effects, accelerometer output signal has a certain error, in this paper, the fast Fourier transform (FFT) filtering, achieved desired results. In addition, the accelerometer due to hardware factors and the environmental impact of electrical, output with a certain amount of drift, according to the experimental test, this paper tests the amount of the output drift, and calibration of the output equivalent. Acceleration of information-based compound control to improve the beam stability of the entire system under the simulink simulation, the simulation results show that the method has obvious effect to improve beam stability, reducing the overshoot, shorter settling time, tracking error significantly reduced.Finally, the paper is summarized, and improve the beam stability control technology development is prospected.
