Controller Design of High-Speed Maglev Train Levitation System

In this chapter, a mathematical model of the levitation system based on the joint structure is firstly established and analyzed. After simplifying the model, a nominal controller of the levitation system is designed by adoption of the linear quadratic regulator (LQR). For issues of the track irregularities and propulsion disturbance, the active disturbance rejection control (ADRC) algorithm is proposed. A high-speed maglev train levitation control test platform is then built, and the high-speed maglev hardware and software systems are designed and implemented. The levitation system performance experiments are conducted to verify the effectiveness of the proposed levitation control algorithms.
