Abstract:

Based on the working mechanism and control principle of the laser platform-type seeker, this paper analyzes the influencing factors of the angular velocity noise and disturbance rejection rate,and puts forward measures to improve the disturbance rejection rate. A laser platform lead model and disturbance rejection rate model based on torque disturbance are constructed, and a test platform was built. Through comparative and analysis of simulation and test results, the factors affecting of disturbance rejection rate are verified, and the effectiveness of measures to improve disturbance rejection rate and reduce the angular velocity noise of sight are verified, that can meet the requirements of engineering applications in rocket environments.
