基于太极阴阳对偶律的北斗高精度抗差自适应滤波算 法与工程架构设计 Based on the Taiji Yin-Yang Duality Law: BeiDou High-Precision Robust Adaptive Filtering Algorithm and Engineering Architecture Design

针对北斗卫星导航系统(BDS)在复杂环境下受电离层延迟与多路径效应影响导致精度受 限的瓶颈,本文提出一种基于太极统一场论的抗差自适应滤波算法。传统方案多采用对抗 式滤波与模型修正,存在理论自洽性不足、高动态环境易发散等问题。本文将接收机维持 时空基准的测距参考系定义为"阳场",将电离层、多路径等微观环境扰动定义为"阴场",电 磁信号作为对偶纽带。基于"阴阳流转"与"量变质变"哲学基础,构建了引入双曲正切函数 (tanh)的非线性动态阻尼机制(活秤砣算法),并给出其状态空间方程与李雅普诺夫 (Lyapunov)稳定性证明。在模拟真实北斗复杂突变环境(20 米级多路径干扰)的 C++底 层仿真中,该算法能够瞬时激发最大阻尼(由 0.58 跃升至 0.79),有效抑制误差发散, 并在干扰消失后迅速回归基准态(误差<0.1m)。结果表明,该范式将传统"消除干扰"的被 动策略升级为"动态平衡与利用"的主动控制,为北斗高精度定位突破厘米级至晶格级瓶颈 提供了全新的理论视角与工程落地方案。 Aiming at the bottleneck that the Beidou Navigation Satellite System (BDS) suffers from limited positioning accuracy in complex environments due to ionospheric delay and multipath effects, this paper proposes a robust adaptive filtering algorithm based on the Taiji Unified Field Theory. Traditional solutions mostly adopt adversarial filtering and model correction, which suffer from insufficient theoretical self-consistency and easy divergence in high-dynamic environments. This paper defines the ranging reference frame in which the receiver maintains the spatiotemporal datum as the "Yang field", and defines microscopic environmental disturbances such as the ionosphere and multipath as the "Yin field", with electromagnetic signals serving as the dual coupling. Based on the philosophical foundations of "Yin-Yang circulation" and "quantitative change leading to qualitative change", a nonlinear dynamic damping mechanism (the "Living Counterweight" algorithm) introducing the hyperbolic tangent function (tanh) is constructed, and its state-space equations and Lyapunov stability proof are provided. In C++ low-level simulations mimicking real Beidou complex transient environments (20-meter-level multipath interference), the algorithm can instantly excite maximum damping (jumping from 0.58 to 0.79), effectively suppressing error divergence, and rapidly returning to the datum state (error < 0.1 m) after the interference disappears. The results show that this paradigm upgrades the traditional passive strategy of "eliminating interference" into an active control of "dynamic balance and utilization", providing a new theoretical perspective and engineering implementation scheme for Beidou high-precision positioning to break through the bottleneck from centimeter-level to lattice-level.
