| 摘 要： | 电磁型磁浮列车的悬浮系统为典型的非线性系统,经常受到外界扰动影响而失去稳定。针对悬浮系统的这种特点,设计一种干扰补偿的非线性悬浮控制器:在合理假设的基础上,建立EMS型磁浮列车悬浮系统的非线性数学模型;通过反馈线性化将该非线性模型精确线性化,得到等价的线性模型。然后,设计将反馈线性化补偿与扩张状态观测器相结合的悬浮控制器,利用外部扰动观测值对悬浮系统进行补偿。这一设计可大幅度提高悬浮系统的抗干扰能力。仿真实验结果表明,该控制器的控制性能明显优于基于反馈线性化方法设计的控制器,对干扰具有更强的鲁棒性。

| Abstract: | The technology of magnetic suspension control is one of the key technologies of the maglev train.The magnetic suspension system is a typical nonlinear system and loses stability because of external disturbance.Aiming at this characteristic of the magnetic suspension system,a nonlinear controller based on disturbance compensation was designed.Firstly a nonlinear mathematical model of the magnetic suspension system was derived under some reasonable assumptions.Then the model was linearized exactly by means of... |
