本文提出了一种新的非线性控制系统,实现了仅使用电磁铁的磁悬浮轴承系统的零功率控制。通过仿真和实验表明,本文提出的非线性控制是实现磁悬浮轴承系统零功率控制的一种非常有用的方法。此外,由于非线性控制的存在,对于偏离平衡点较大的情况,该控制策略具有很强的镇定能力。基于李亚普诺夫直接法设计了非线性控制系统。根据转子的位移和速度,采用非线性算法实现电磁铁的切换。由于非线性控制系统只由两个参数组成,因此设计起来非常容易。此外,闭环系统的特性也可以很容易地改变。
This paper proposes new nonlinear control system to realize a zero power control of magnetic bearing system using only electromagnets. It is clarified through the simulation and experiment that the proposed nonlinear control this paper is a very useful approach to realize a zero power control of magnetic bearing system. Also, this proposed control strategy will be very powerful to stabilize for big deviations from the equilibrium point because of nonlinear control. The nonlinear control system is designed based on Lyapunov's direct method. The electromagnets is switched by the nonlinear algorithm depend on the displacement and the velocity of a rotor. It is very easy to design the nonlinear control system because it consists of only two parameters. Also, the characteristics of closed loop can be changed easily.
