摘要

针对高动态环境下北斗卫星接收机锁相环（phase locked loop，PLL）PLL的性能优化问题，提出了一种基于自适应光滑非线性函数的三阶锁相环设计方法，解决了传统分段非线性环路中的相位突变和噪声敏感性问题。仿真实验结果显示该方法在复杂噪声环境和动态场景下的稳定性、收敛速度及抗干扰能力更佳，验证了其在复杂动态环境下的鲁棒性与实用性。通过理论创新与实验验证，为高动态全球导航卫星系统接收机提供了兼具快速响应与强抗扰能力的PLL解决方案，具有明确的工程应用前景。

Abstract

This paper addressed the performance optimization of the BeiDou satellite receiver phase-locked loop in high-dynamic environments by proposing a third-order PLL design based on an adaptive smooth nonlinear function. Through an innovative approach

it resolved the issues of phase mutation and noise sensitivity inherent in traditional piecewise nonlinear loops. Simulation experiments demonstrated superior stability

convergence speed

and anti-interference capability under complex noise conditions and dynamic scenarios

validating its robustness and practicality in highly dynamic environments. By combining theoretical innovation with experimental verification

this research provided a PLL solution for high-dynamic GNSS receivers that balanced rapid response with strong disturbance resistance

offering clear prospects for engineering applications.
