Nonlinear decoupling control of the join-structure in a maglev train
磁浮列车搭接结构的非线性解耦控制

The join-structure of maglev train is a multiple-input and multiple-output(MIMO) nonlinear system; the smooth control of which plays an important role in the reliability of the maglev train. The system is decoupled by using the differential geometry theory. The decoupled system is then linearized through feedback linearization method, which ensures the global stability of the system. In order to guarantee the dynamic property of the system, the pole-displacement method is applied to the decoupled and linearized system. Finally, an example is given to illustrate the control approach.
