Abstract :
Lap structure is a basic component unit of the permanent magnet electromagnetic hybrid maglev train. To control the lap structure is the key to the stable operation of the maglev trains. This paper firstly established the mathematical model of the lap structure, which makes the order reduction of the model through the design current loop. Due to the lap structure can be stable at the balance point, carry out linearization mathematical model to the lap structure. The state observer is adopted to measure the state which cannot be measured. Finally carry out the optimal control algorithm to control the lap structure. The simulation results show that the controller can make the permanent magnet electromagnetic maglev trains be stable suspension.
