摘要
风力摆控制系统作为一种典型的自动化控制平台,近年来得到了广泛的研究。为了更科学合理地运用风力摆,设计并制作了一套基于单摆物理模型的实物系统,为系统预设了定角度直线运动和圆周运动两种主要形式。对运动过程进行了线性化、离散化处理,将两种运动都分解为两个正交方向的简谐运动,利用莉萨如图形完成算法的设计。利用单片机的定时器产生系统的控制周期,在一个控制周期内完成采样、计算、输出、执行。试验结果表明,系统可以稳定、精确、快速地完成预设的目标动作,且抗干扰能力强,响应快。
As a typical automatic control platform, wind pendulum control system is studied extensively in recent years. In order to apply the wind pendulum more scientifically and rationally, a kind of object system based on simple pendulum physical model is designed and manufactured. The system has two main forms: fixed angle linear motion and circular motion. The motion process is linearized and discretized, and they are decomposed into two orthogonal directions of harmonic motion.The algorithm is designed by using Lissajous-Figure. The control cycle is generated by the timer of the single-chip, and the sampling, calculation, output and execution are completed within a control cycle. The results show that the system can achieve the preset target motion stably, accurately and rapidly, and has strong anti-interference ability and fast response.
