代码说明:

  四旋翼无人机是一种具有六个自由度和四个输入的欠驱动强耦合、外型新颖结构简单的飞行器。由于其具有制造成本地、重量轻、体积小、操作简单、使用方便、隐身性好、对作战环境要求低的特点,使其能准确、高效的执行各种军事或民用任务,因此四旋翼无人机具有一定的军事和民用价值。本课题针对四旋翼无人机的特点和飞行原理,对其动力学分析以及运动控制的研究,利用牛顿—欧拉方程,建立了四旋翼无人机的动力学模型,并针对该模型设计了PID四通道控制系统,且在Matlab/Simulink仿真平台上,利用PID控制系统对四旋翼无人机进行仿真,完成了对四旋翼无人机运动控制和与地面运动物体的交会,仿真结果表明:仅仅通过改变四只旋翼的转速来改变升力,进而改变四旋翼无人机的姿态控制和位置控制,从而实现了四旋翼无人机的运动控制以及与地面运动物体的交会。(Height Control of Four-Rotor Aircraft)

  • 黑盒B-BOX 无限制版
    无限制版,极影工作室的看家产品之一,交易两个货币兑进行对冲。经过实际测试,EURUSD和GBPUSD的盈利效果最好,AUDUSD和NZDUSD不是很好。按理说这两组关联都不错才对,可能是测试期间行情所致,因为无法回测双币以上ea,实盘模拟测试。(One of the Housekeeping Products of Polarshadow Studio is trading two currencies to hedge against each other. After actual testing, EURUSD and GBPUSD have the best profitability, while AUDUSD and NZDUSD are not very good. It is reasonable to say that the correlation between the two groups is good, which may be due to the market during the test period, because it is impossible to retest the EA above two coins, a real-time simulation test.)
