非线性控制在磁悬浮系统中的应用

Non-linear Systems Theory Applied to Magnetic Suspension Systems

用滑模变结构控制原理设计磁悬浮系统非线性控制器，并在磁悬浮球装置上进行了试验，结果证实这种控制器具有完全的鲁棒性、良好的参数适应性，设计方法也有广泛的适用性。悬浮系统的刚度有显著的提高。

An experiment has been made on the device of magnetic suspending ball to test the effect of the controller designed according to the theory of variable structure control system. The result proves that this kind of controller has the better robusticity of rubust and increases the rigidity of the suspension system. And it is easier to design the controller using the theory of variable structure control systems. Further more this theory can be applied to on all kinds of systems.
