基于dsPIC30F4013控制器旋转角度检测系统的研究

Research of Rotation Angle Measurement System Based on dsPIC30F4013 Controller

角度检测技术一般是采用两相正交霍尔传感器的方法进行检测,针对高精度的角度检测的需要,提出了一种差分传感器的角度检测系统。阐述了霍尔传感器的工作原理,并基于dsPIC30F4013单片机角度检测系统的检测精度进行了论述。根据实践检测可知,该系统能更有效的提高角度检测精度。

The technology of angle detection is generally through the method of photoelectrical sensor orthogonality. This paper aims at requirement of the angle detection accuracy,the method of separate measurement system is designed .In this paper,the principle of KMI16/1 and the measurement method of four sensor separation in this position detection system are first introduced in detail, then the software and harsware in the position detection system based on dsPIC30F4013 are introduced in detail.
