舰载机纵向自动着舰控制

Research on a carrier-based automatic longitudinal aircraft landing control system

对舰载机纵向着舰控制系统进了分析和研究,根据舰船甲板运动引起舰载机着舰点不断变化的问题,加入甲板运动补偿环节,并对补偿律进行了设计;对常规的纵向导引控制律进行了改进设计,引入模糊控制.仿真结果表明,引入甲板运动补偿环节,有效地减小了由于甲板运动造成的着舰误差,提高了着舰的安全性,模糊PID导引控制律比常规的PID导引控制律具有更好的控制下滑轨迹的能力,更能满足着舰的需要.

A study was conducted on a carrier-based aircraft landing control system.Based on the fact that ship deck motion causes constant changes in the carrier-based aircraft landing points,deck motion compensation segments were added and the compensation law was re-designed.The conventional vertical guidance control law was improved through the introduction of a fuzzy PID guidance control.The simulation results indicate that the carrier-based aircraft landing error was effectively reduced and the security performance of the landing was enhanced with the application of ship deck motion compensation segments.The results also demonstrate that the fuzzy PID direction guidance control law is superior to the conventional PID guidance control law in controlling the carrier-based aircraft gliding routine,better satisfying the requirements of the carrier-based aircraft landing.
