摘　　要：利用动力学和电磁学方法建立了磁悬浮系统的数学模型,分析了系统的刚度阻尼与控制系统之间的关系,在数学模型的基础上以自校正PID结构针对磁悬浮平台设计了非线性控制器,并在磁悬浮平台上进行了实验,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,同时具有广泛的适用性。A math model is built for a magnetic suspension platform based on the electromagnetic dynamics and the voltage balance of an elecromagnetic coil. The relation is analysed between the system stiffness damping and the control system. An experiment has been made on the magnetic suspension platform to test the effect of the nonlinear controller designed with the theory of a self-tuning PID control system. The result shows that this kind controller has a better robust character and can increase the rigidity of the suspesion system. Further more, this theory can be used in all kinds of control system.
