The motion planning for the DFS directly affects the accuracy of the G-load simulations. This paper describes a real-time motion planning algorithm for a flight simulator. The G-load simulation model is given but is difficult to solve when the G-loads are negative. A real-time motion planning algorithm with two-dimensional interpolation is used to generate both a trapezoidal G-load curve and three-axis G-load commands. The simulation results show that the simulated G-loads precisely track the commands. The algorithm is accurate and practical. %K 动态飞行模拟器 %K 运动规划 %K 过载模拟 %K 2维插值 %K < %K br> %K dynamic flight simulator %K motion planning %K G-load simulation %K two-dimensional interpolation %U http://jst.tsinghuajournals.com/CN/Y2015/V55/I7/709#FigureTableTab
