Control Algorithm And System Implementation Of Buoy Communication System Stabilization Platform

In modern warfare,the concealment of communication determines the life cycle of the combat platform.In order to improve the concealment of the underwater combat platform in the marine environment,the combat platform has gradually become the main communication method of marine combat by releasing the towed buoy underwater to communicate with the satellite.However,due to the influence of the ocean climate,the buoy has irregular movements,and its shaking will cause data transmission to be interrupted,which greatly limits the communication efficiency between the buoy and the satellite.The special control platform of the classic satellite mobile communication system is mainly aimed at land mobile stations,and is not suitable for sea buoy and satellite communication scenarios.To this end,the paper designs and develops a set of self-stabilizing control platform for buoy satellite communication system,improves the attitude stability accuracy of buoy satellite communication system,solves the problem of stable communication of towed buoy under the disturbance of marine meteorological environment,and provides a new type of hidden communication for underwater combat platform means.The main contents of the design and development of the self-stabilizing control platform of the buoy satellite communication system are:1.Is designed the stabilization gimbal control system to realize the attitude stability control of the buoy satellite communication system under the lateral disturbance of ocean waves.The system selects a two-degree-of-freedom gimbal,uses the PID control algorithm to realize the stabilization control of the gimbal,and introduces the Kalman filter algorithm to predict the attitude of the buoy at the next moment,and solves the problem of PID control algorithm response lag.Through experimental tests,the accuracy of the attitude stability of the two-degree-of-freedom gimbal is controlled within 3 °,which satisfies the attitude stability conditions of the load of the buoy satellite communication system.2.The wave model is established to improve the control accuracy of the buoy stabilization gimbal.Use the PM spectrum to construct a wave model,and combine the buoy structure parameters to construct a transfer function,construct a buoy motion space state model,buoy motion attitude data,provide parameters for the Kalman filter algorithm,construct a Kalman filter model,and verify the feasibility of the model through simulation.Provide a theoretical basis for hardware to implement Kalman filtering.3.In order to solve the problem of the carrier of satellite communication equipment in the marine environment,the shape and structure of the buoy were designed according to the relevant parameters of the satellite communication equipment.The main contentincludes the structure selection of the standard body,the main size design,the stability and movement performance of the buoy,etc.
