摘要

现代控制工业应用中最重要的要求是电机转子轴角的测量。解析器是一种绝对角度位置测量传感器，但它需要一定的信号处理技术来提高角度的跟踪精度。利用改进的角度跟踪观测器(ATO)脉冲激励算法，讨论了旋转器到数字转换器(RDC)的数学设计分析。在MATLAB®SIMULINK®中实现了基于软件的RDC系统，并通过不同速度范围的角度跟踪性能进行了验证。结果表明，所设计的RDC系统具有较好的跟踪性能，误差可忽略不计，降低了硬件成本、重量和尺寸。

Modified ATO algorithm based high accuracy RDC using pulse excitation

Most important requirement in the modern control industry applications is the measurement of motor rotor shaft angle. Resolvers are absolute angular position measurement transducers, but it requires some signal processing techniques to improve the tracking accuracy of the angle. This paper discusses the mathematical design analysis of Resolver to Digital Converter (RDC) using modified Angle Tracking Observer (ATO) algorithm with pulse excitation. The proposed software based RDC system is implemented in MATLAB® SIMULINK® and the angle tracking performance is verified through various ranges of speed. The results show that the designed RDC system provides better tracking performance with negligible error and it reduces the hardware cost, weight and size.
