摘要
针对一种微型万向平台,介绍了其构成情况、工作原理及典型应用。通过建立的几何模型,分析了其姿态控制方法。阐述并分析了Preisach迟滞模型并进行了数字仿真。结果表明采用Preisach模型的迟滞补偿方法对该微型万向平台的SMA进行驱动时,可有效提高控制响应;该方法可较容易地预测经过任意序列输入参数以后的输出情况。
Regarding one micro rotating platform,its structure,work principle and typical application are introduced respectively.Through building its geometry model,the attitude control model is also set up.Based on the characters of SMA and Preisach model,the digital simulation is done.The results show that this control method by Preisach model is feasible.And the output could be calculated easily when arbitrary input.This research has provided the useful reference for such kind of study.
