摘要
随着分数阶理论研究的不断发展,分数阶控制器方法不仅可以改善系统动态响应特性,而且可以获得优越于传统PID控制器方法。分数阶微积分控制器增加了积分阶次和微分阶次,提高了设计控制器的灵活度。本文在分数阶理论基础上引入了自抗扰控制器,设计出新型的分数阶自抗扰控制器,充分结合分数阶控制器高精度控制和自抗扰控制器抗干扰能力强等优势。通过仿真分析的得出分数阶自抗扰控制器的控制效果优越于其单独的控制效果。
With the continuous development of the fractional-order theory,fractional-order controller method can not only improve the dynamic response characteristics, but also can obtained superior to the conventional PID controller method.Fractional calculus controller increases the integral and differential, improve the the flexibility of the controller. In this paper,based on the fractional-order theory added ADRC, design fractional-order active disturbance rejection controller, combine fractional order controllers precision control with ADRC disturbance rejection ability. Through simulation analysis fractionalorder active disturbance rejection controller results superior to their individual control.
