A discussion is devoted to the study of intelligent control methods and technologies of real-time distributed 3-dimensional animation simulation for the super-maneuverable attack of new generational fighter in this paper. A flight control system of super-maneuver is reconstructed by adopting three layers BP neural networks of number 3, and the fire/flight coupler is designed by introducing a fuzzy control rule whose universe of discourse and gain are regulated adaptively on the line. Furthermore, a new method of real-time distributed 3-dimensional animation simulation is put forward, and a real-time distributed 3-dimensional animation simulation tool platform is constructed in this paper. The simulation result is lifelike, perceivable directly and useful.展开更多

文摘为提高自动紧急制动系统对行人保护的安全性,提出了一种采用上层模糊控制和下层PID(proportion integration differentiation)控制的分层控制行人避撞策略。以某款E级SUV车辆为研究对象,建立其动力学模型,在国内外真实行人测试场景下,构建了基于TTC(time to collision)碰撞时间理论的风险评估模型,通过Matlab和CarSim软件的联合仿真,对控制策略进行了仿真验证。仿真结果表明:所提出的自动紧急制动系统行人避撞策略能满足国内行人测试工况标准,与行人最小安全距离为0.9m;在保证安全的前提下,模糊控制可自动调节制动强度,输出减速度范围控制在4.8～6.1m/s2,有较好的舒适性;TTC风险评估模型正确发出了行人碰撞预警,无漏警和误警发生。
