摘要:

磁悬浮系统(Maglev)是一种非线性系统,通过磁力场使物体悬空而不依赖其他支撑。Maglev系统的主要控制目标是通过电磁力在空气中悬浮钢球。然而,Maglev系统具有高度非线性动力学,这在敏感控制和调节非线性动力学方面存在不便。本文提出了一种基于分数阶导数的非线性反步控制器,用于控制非线性电流控制Maglev系统。随后给出了系统动力学和分数阶反步控制器设计,通过Lyapunov理论证明闭环系统的渐近稳定性。一些基于计算机的数值实验被进行以展示所提控制器对Maglev系统控制的有效性。

英文摘要:

The magnetic levitation system (Maglev) is a nonlinear system by which an object is suspended with no support other than magnetic fields. The main control perspective of the Maglev system is to levitate a steel ball in air by the electromagnetic force. However, the Maglev system has highly nonlinear dynamics which is inconvenient in the sense of sensitive control/regulation of its nonlinear dynamics. In this paper, the nonlinear backstepping controller based on the fractional-order derivative is proposed for the control of the nonlinear current-controlled Maglev system. After, the system dynamics and fractional-order backstepping controller design are given, the asymptotic stability of the closed-loop system is proved by employing the Lyapunov theory. Some computer-based numerical experiments are carried out to show the effectiveness of the proposed controller for the control of Maglev system.
