摘要

解析器是一种角度位置传感器,用于要求鲁棒性和可靠性的应用,例如电动汽车。然而,从解析器输出信号中获取角度位置是一项困难的任务,提出了许多算法来实现这一任务。本文介绍了模型预测控制(MPC)在求解旋转器信号中的应用。采用同步解调的方法得到解析器输出的包络信号,得到估计误差。将传统模型预测控制器的结构改进为角度跟踪观测器(ATO)。仿真结果表明了该方法的有效性。根据文献综述,这是第一次将模型预测控制作为观测器从旋转器信号中获取角度位置。

Application of Model Predictive Control in a Resolver-to-Digital Converter
A resolver is an angular position sensor used in applications that demands robustness and reliability, such as electric vehicles. However, getting the angular position from resolver output signals is a difficult task, and many algorithms were proposed to achieve that task. This paper describes the application of model predictive control (MPC) to get the angular position from resolver signals. Synchronous demodulation is used to get the envelopes of the resolver outputs and get the estimation error. The structure of the conventional model predictive controller was modified to be used as an angle tracking observer (ATO). Simulations show the performance of the proposed approach. According to the bibliographic review of the authors, it is the first time that model predictive control is applied as an observer to get the angular position from resolver signals.
