摘要: 本文完成了船舶卫星接收系统减振控制的设计，通过振动分析建立系统动力学模型，选用UM2082F08单片机作为主控器，搭配AD9251模数转换芯片、SS6809A电机驱动芯片及YA19T加速度传感器，构建闭环减振控制系统。系统通过实时检测振动频率与幅值，动态调节减振器内硅胶液体体积以改变固有频率，规避共振风险。实验结果表明，该控制设备可实现全自动化运行，频率响应时间为0.01 s，共振回避率为100%，振动幅值控制在0~2.5 cm内，有效延长设备使用寿命，降低维护成本30%以上。

Abstract: This paper completes the design of vibration reduction control for the ship satellite receiving system. A dynamic model of the system is established through vibration analysis, with the UM2082F08 single-chip microcomputer as the main controller, combined with the AD9251 analog-to-digital conversion chip, S56809A motor driver chip and YA19T acceleration sensor to construct a closed-loop vibration reduction control system. The system dynamically adjusts the volume of silicone fluid in the shock absorber to change the natural frequency by real-time detection of vibration frequency and amplitude, thereby avoiding resonance risks. Experimental results show that the control equipment can realize fully automatic operation, with a frequency response time of 0.01 s and a resonance avoidance rate of 100%. The vibration amplitude is controlled within the range of 0~2.5 cm, which effectively extends the service life of the equipment and reduces maintenance costs by more than 30%.
