摘要
针对常规着舰控制只根据当前指令和状态信息导致控制性能有较大瓶颈问题,设计基于未来信息的着舰预见控制器.首先采用离散Kalman最优滤波进行甲板运动预报,然后将甲板运动预报的未来信息和基准下滑道的未来信息加入到着舰纵向预见控制中.实验结果显示,加入未来信息和预见控制器能大幅增强飞机跟踪基准下滑道和甲板运动的能力,显著减少系统相位滞后,改善控制精度和动态性能等.基于未来信息的着舰纵向预见控制,可以突破常规着舰控制性能的上限.
Abstract
For the issue of significant carrier control performance bottlenecks in conventional landing control,which only relies on current instructions and state information,a preview controller of carri-er landing based on future information is designed.Firstly,discrete Kalman optimal filtering was used for deck motion prediction.Then,the future information of the deck motion prediction and the reference glide slope were added to the longitudinal preview control of carrier landing.Experimental results show that incorporating future information and preview controller can significantly enhance the aircraft's ability to track reference glide slope and deck motion,significantly reduce system phase lag,and improve control accuracy and dynamic performance.The longitudinal preview control of carrier landing based on future information can break through the upper limit of conventional landing control performance.
