摘要

为实现对转轴的有效监控，设计并实现了角度跟踪系统。一个关键的焦点是最大限度地减少系统的非线性。本设计集成了级联磁阻传感器，输出对应于动轴旋转的模拟正弦和余弦信号。这些信号通过电压-频率（V/F）转换器转换成频率输出，从而实现强大的数字处理。为了提高系统的线性度，采用了三种线性化技术，并进行了对比分析。仿真和实验评估证实，采用线性化方案- c，系统具有良好的线性度。该方案在理想情况和实际情况下的非线性百分比分别为0.00335%和0.1143%，而在理想情况和实际情况下的百分比误差分别为0.00334%和0.1143%。由此产生的系统设计紧凑，具有成本效益，适用于一系列工业自动化和机器人应用，其中精确的角度反馈是必不可少的。

Design of electronic system for linearization of sinusoidal characteristics of cascaded tunneling magneto-resistance sensor

This paper presents the design and implementation of angle tracking system for efficient monitoring of rotating shaft. A key focus is minimizing system non-linearity to the maximum extent. This design integrates a cascaded magneto-resistance sensor that outputs analog sine and cosine signals corresponding to the rotation of moving shaft. These signals are converted into frequency outputs using a voltage-to-frequency (V/F) converter, allowing for robust digital processing. Three linearization techniques are applied and comparatively analyzed to improve system linearity. Simulation and experimental evaluations confirm that the system delivers excellent linearity with the linearizing scheme-C. The obtained percentage non-linearity in this scheme for ideal and practical case are 0.00335%, 0.1143% respectively whereas the percentage error is 0.00334% in ideal case and 0.1143% in practical situation. The resulting system design is compact, cost-effective, and suitable for a range of industrial automation and robotics applications where precise angular feedback is essential.
