摘要
介绍了分数阶微积分的历史、定义、性质及国内外研究状况,分析了分数阶PIλDμ控制器的特性、参数整定、稳定性条件、数字实现方法及其在飞行控制中的发展前景。研究表明,分数阶控制器具有更大的灵活性、更强的鲁棒性,并能提高系统的稳定性和精度,在飞行控制系统中有广泛的应用前景。
The history, definition, character and studying status of fractional calculus at home and abroad were demonstrated in this paper. The trait, tuning of parameters, stabilization condition, digital implementation and development of the fractional order controller in the flight control were also presented. The research result showed that the fractional order controller had more flexibility and robustness, which could improve the performance of the control system. It had bright future in the application on the flight control system.
