摘要: 为了提高陀螺仪的测量精度,基于神经网络代数算法提出一种新的非线性误差补偿模型。由于该算法将复杂非线性优化问题转化为线性代数方程组问题,所以该模型具有速度快、实时性好,能实现样本空间精确映射的优点。通过实验对比证明该模型比曲线拟合精度要高。多次重复性实验证明该模型能够将误差限制在0.1o/s以内,满足实际控制要求。

Abstract: To improve measurement precision of gyroscope, a novel nonlinear error compensation model is proposed using an algebra algorithm of neural networks. The model has advantages of real-time processing and precision mapping in the sample space because the algorithm transforms the complicated nonlinear optimization problem into linear algebraic equations. Compared to polynomial fitting, the proposed model has better precision. Experiments show that the model can reduce error to 0.1o/s and meet practical control needs.
