Abstract

The photoelectric theodolite is an important device for photoelectric tracking measurement, and has the functions of real-time monitoring and automatic tracking. With the continuous improvement of the optical theodolite tracking measurement requirements, various traditional training and testing methods have appeared various deficiencies. This paper takes the photoelectric theodolite servo tracking system as the research object, and based on the momentum moment theorem and Euler's dynamic equations, a non-linear two-axis coupled dynamics model of the tracking frame in the system is derived. The electromechanical dynamics model describing the dynamic characteristics of the controlled object in the tracking servo system was used. The correctness of the theoretical model was verified by comparison test method and computer simulation method. For the follow-up research, the design of high-precision tracking controller and control parameter selection. And optimization provides a theoretical reference and model basis. The experiments in this article show that the optimized photoelectric theodolite car model has fully met the requirements in terms of vibration intensity, and the maximum vibration intensity can be controlled to reach less than 80% of the technical requirements of the photoelectric theodolite (≤0.5g), indicating the addition of a vibration isolation device . The ride comfort of the photoelectric theodolite has been significantly improved.
