Design of Model Reference Adaptive Controller for Active Guidance System of High Speed Maglev Train

The electromagnetic suspension type high-speed maglev train guidance system is an unstable system and requires active control. When the train passes the curve or is subjected to cross wind, the vehicle body will be greatly disturbed. In order to ensure that the guidance control system maintains good control performance, a model reference adaptive controller is designed. First, a model of a dual electromagnet guidance system was established. The design of the current loop reduces the response delay of the electromagnet and reduces the order of the system. Based on Lyapunov stability theory, an adaptive mechanism is designed so that the gap state of the controlled object can follow the gap state of the reference model. Simulation results show that the system can maintain good control performance under different disturbance dynamics.
