The research on Electromagnetic Aircraft Launcher method

Electromagnetic Aircraft Launcher technology (EMALS) is a specific emission technology, which is a major breakthrough in the traditional catapult way. Electromagnetic energy is used in driven objects during catapult. Theoretical analysis shows that EMALS can achieve high-speed ejection of large objects. The paper focused on the simulation of control subsystem study. Current, velocity, position closed loop model is used in modeling. To control the motor, vector control and space vector pulse width modulation (SVPWM) is adopted. The simulation result completely decouples torque and excitation component, and also has fast response and small steady-state error. The model is able to meet the higher performance and system feasibility.
