Research on Electromagnetic Aircraft Launch System Based on Gray Control

电磁弹射系统相比于传统的蒸汽弹射系统,具有推力强、体积小、质量小、利用率高等优势,但系统的控制效率及精度不高成为当下急需解决的严峻问题.永磁直线同步电机伺服控制系统作为电磁弹射系统的核心,其性能好坏是影响电磁弹射装置的重要因素之一.对于伺服控制系统中的灰色不明确部分,以灰色理论为依据,加入灰色PID控制算法,创建灰色模型,并施以预测补偿.仿真实验及研究表明,与传统的PID控制策略相比,使用灰色PID控制有助于提高系统性能,有效抑制干扰的同时明显提高控制精度.

Compared with steam catapult,electromagnetic aircraft launch system（EMALS）,which has advantages of high thrust density,small volume,light weight,high efficiency,high control precision,become the focus in recent years.Permanent magnet linear synchronous motor（PMLSM）ac servo control system,which is the core of EMALS,will directly affects the control of device efficiency and accuracy.Based on the gray theory,constructing the gray PID control algorithm,agray model is set up for of the uncertain part in the servo system,and to forecast the compensation.Simulation experiments show that the application of gray PID control in servo system,can effectively suppress interference,improve the control accuracy and achieve ideal control effect.
